SAS vs. NBA: Basketball Bodies

Health, Media

Spurs_on_court

Many NBA stars are built like NFL players.  That is, except for the San Antonio Spurs.

Kawhi Leonard actually has some pretty beefy muscles.  But he’s the “biggest” on the team, by far; his built-up muscles are atypical for San Antonio.

Compare a few famous physiques:

NBA                                                                                     NFL

SF  Lebron James — 6-8 / 260 lbs.                  DE  J.J. Watt — 6-6 / 240 lbs.

SF  Larry Johnson — 6-7 / 250                          LB  Lawrence Taylor — 6-6 / 250

SG  Derek Fisher — 6-1 / 210                              RB  Reggie Bush — 6-0 / 203 lbs.

 

Think about those numbers.  Compare Michael Jordan’s height / weight:

SG  Michael Jordan:  6-6 / 216 lbs.

SG  Dwyane Wade:  6-2 / 220 lbs.

And Jordan was big for the league of his day.  When he first entered the league, MJ weighed only 200 pounds.  He bulked up after the Pistons manhandled him in both the 1989 and 1990 Eastern Conference Finals using their new defensive strategy, the “Jordan Rules.”  Jordan himself attributes his 1991 success in defeating the Jordan Rules to his increased power and bulk from off-season strength training.  (See ESPN Films, 30 for 30 Bad Boys.)

This seems to mark the beginning of the arms race in ever more massive NBA bodies.  The trend’s logical conclusion?  Shaquille O’Neal, heaviest (and, some would argue, most overrated) NBA star of all-time.  Shaq scored a lot, passed the ball little.  If you’re seven feet tall, have explosive strength, and you weigh 100+ pounds more than the individual guarding you, why wouldn’t you?

Shaq offensive foul

 

Too many NBA teams today feature an incredibly powerful superstar, give him the ball, and have him fly at the rim, scattering smaller defenders like bowling pins.  It makes for some eye-popping individual player highlights.  But I prefer team ball.

Ball movement is NBA conventional wisdom.  But it’s also something of a lost art.  The TV-announcer euphemism for high-time-of-possession individuals is the “go-to” player; NBA coaches use the term “ball stopper.”  That term indicates the stoppage of ball movement on offense, not on defense.  While there’s nothing about built-up muscles that prevents a player from passing the ball, if you were bigger, stronger, and faster than nine of ten players on the floor, it would seem a rational choice to keep the ball and score 35 points.

It’s a legitimate choice, I suppose.  But is it merely a distraction from the true team-nature of basketball?  Is it just a coincidence that Coach Popovich has put together his team without any players that could pass for an NFL linebacker?

Some of the league’s current young guns:

eric bledsoe_576x324Eric Bledsoe — 6-1 / 200 lbs.
dwight-howard-mens-healthDwight Howard — 6-10 / 265

 

7-corey-magette

Corey Magette — 6-5 / 225

This is a shoe the Spurs just don’t fit.

 

Spurs championship team larger

 

Am I right?  I mean, think about this collection of guys.

Tony Parker — 6-1 / 180 lbs.

Manu Ginobli — 6-6 / 200 lbs.

Danny Green — 6-6 / 205

Kawhi Leonard — 6-7 / 225

Matt Bonner — 6-10 / 235

Tim Duncan — 7-0 / 250

Of their amazing 2014 Finals dominance, Manu Ginobili commented on how “differently” the Spurs play.  In the Bleacher Report piece “Passing stats Illustrate Spurs Dominance in Finals,” Ginobili says “if you don’t have as much talent, you still can do it. You can move the ball and put a lot of pressure on the defense.”  He may as well have said “if you don’t have as much muscle . . .”

Judging from their bodies, as a team, the Spurs don’t just play different.  They are different.

Why Knives Chip and What to Do About It

I recently found this knife of ours had become chipped pretty badly. I didn’t care all that much. Not only was it a castoff from a friend who’d downsized her kitchen. It was just a $40 item from Chicago Cutlery. Had the chipping appeared on our $140 Wusthof chef’s knife, I would have cared a lot.

This knife? Nah. When I found it chipped, I sneered briefly planned obsolescence. My Filipino parents would say of this scenario sayang, as in, What a waste.

knife chipping closeup - snip tool

I cook without my reading glasses, so didn’t notice the chipping ’til it got pretty bad.

Turns out, I should have been sayang-ing at myself. The chipping wasn’t caused by cheap, flawed steel or poor quality control. It was me.

After hand-washing my knives, I stand them on edge to air dry. I learned somewhere that air-drying is best for keeping knives sterile after washing.

Turns out, air-drying is perfect — if you want droplets of water to collect on the cutting edge, weakening the steel as they slowly evaporate. Then, when sharpened, the weak spots flake rather than grind. Hence, the chips.

Now for the happy ending.

By chance in an airport lounge, I learned of my errant ways from The Today Show. A quick Google search then led me to this YouTube tutorial. Have a look-see at how to easily repair a chipped knife.

For regular-maintenance sharpening, I’d been using a rolling-wheel sharpener (below). Bad. Not only is the grain to coarse. Its design makes it impossible to keep a consistent grinding angle. This contributes to the chipping–this blunt instrument (as it were) wreaking havoc on the weakened steel. We do have a rarely used whetstone. I’d never used it because the user manual insists on a technique that’s slow to the point of absurdity. (“Pull the knife toward you five times, for two seconds each time. Then reverse directions, away five times. Repeat this alternating cycle fifty to one hundred times.”)

Wrong! The whetstone used Murray-Carter style (GIF-image, above) is actually a real pleasure. And fast, too.

Bike Maintenance — Five Drops of Oil or One?

Health

bike-maintenance

In September, I put on a new chain. After just two weeks, it started showing rust. Yes, I do lockup outside. But the rust would come even after dry, sun-baked weather. What the hell?

The rust does come off easily. But I found myself having to lube five times a month. Uh, no. I don’t love my bike that much.

So what caused the premature corrosion? Had my LBS (local bicycle shop) sold me an old chain that had been sitting on a back shelf for years? No. With the rust off, the steel plates gleam way too brightly for that scenario. I did switch brands of lubricant earlier in the year. Was that the problem? Couldn’t be — otherwise, my previous chain would’ve demo’d this problem, too.

I’ll cut to the chase. The problem was me.

Yep. I got lazy. Rather than my standard style of chain maintenance, in which I use a lot of oil, I started a new lubing regimen of only a single drop on each link. Just a single drop freed me from the interminable chore of wiping off excess oil. I hate having black, grimy fingers and a backache. With only a single drop per link, I could just wave a towel at my bike from ten feet away and call it done.

The question of “one single drop per link” versus five is a raging debate on the Web.

See: I didn't make it up. All these bike maintenance articles recommend "a single drop" of chain lube.

Countless expert bike maintenance articles recommend “a single drop” of chain lube.

My whole life I’d been in the five-drops camp. Why change now? I’ll tell you why: I’m pushing 50. Hunching over for ten minutes straight to wipe off excess oil is a young man’s game.

Or so I thought.

Using just a single drop may have saved me the initial headache of wiping the chain. But talk about penny wise, pound foolish. Lubing every five days easily tripled my chain-lubing work each month. Now I had this chore six times per month instead of once or twice. I got so tired of crouching down, I splurged on a $130 bike stand, so I could at least I could stand upright. But that meant hoisting my anchor-heavy, 1980’s, steel mountain bike onto the stand and fiddling it into the tricky clamp. And when the weather got too cold to do the work outside, I’d have to carry this beast of a bike (43 lbs. with full fenders and a rack) up two flights of stairs. Did I mention I’m forty-nine years old?

for chain lube blog post smaller

 

Plus, turns out the main reasons I switched to the single-drop method aren’t as persuasive after three months of all this hassle. Back in August, the single-drop advocates had me convinced with their seeming logic:

  • over-lubing creates part-destroying grime;
  • wiping a dirty chain drives grit from the surface to the interior and causes the chain to gnash on itself;
  • ignore this advice, risk a broken chain.

Well, people? I’ve tried it your way. It’s just not worth it. You might be right, my drive train might wear out faster. Or a broken link might strand me on a trail miles from nowhere.

But I don’t give a crap, anymore. I did care for a few months. Never, again.

(I’ve never in my life had a chain break on me. Have you?)

The Babadook: Ghost Story or Psychological Thriller?

Media

the-babadook-book

I watched an exceptionally good horror film on Netflix, called The Babadook. One thing I like to do after seeing a good movie is try to reverse engineer the screenplay. What was the spark that inspired the screenwriter?

In this case the spark was likely a familiar domestic scenario in fiction: what tvtropes.org calls “Maternal Death, Blame the Child” — i.e., the mother dies in childbirth, and the father resents the child.

In this breakout Australian film, the genders are reversed. It’s the father who dies in a horrific auto accident while rushing his pregnant wife to the hospital. Fast-forward seven years, and you have single mother Amelia, struggling to raise her stormy, high-strung son, Sam. The lines on Amelia’s face hint at the toll Sam has taken on her with his eccentric hyperactivity. At just seven years old, Sam has developed a spastic repertoire of magician’s tricks, while fashioning homespun mechanical weapons that shatter windows and break dishes.

 

the babadook - sam in car

 

The film makes clear Sam’s motive in demanding all of his mother’s attention. He’s afraid she doesn’t love him. It’s his greatest fear. And in a horror film, your greatest fear can turn murderous.

Amelia begins to fear this about herself, as well. Has she stopped loving her son? Though her affection for Sam is obvious, her sanity is wearing thin. She puts out Sam’s fires left and right: Sam ejected from school for bad behavior, Sam shoving his cousin out of her tree fort and breaking her nose.

Amelia is also horribly sleep deprived. With Sam’s birthday–also the anniversary of her husband’s death–fast approaching, she’s plagued by nightmares of the car crash that decapitated her husband seven years before.

Sam has nightmares, too. Amelia must soothe him long into the night. The best way is to let him sleep in her bed. But she’s robbed of her own sleep, as he clings to her. In two memorable close-ups, Sam’s hand grips her throat or he grinds his teeth right next to her ear.

As the sleep deprivation wears on her, Amelia begins to lose her temper. She snaps at Sam, curses, even. “If you’re so hungry, why don’t you eat shit!” She apologizes, horrified at herself.

But we’re not surprised. We see she’s on the verge of a nervous breakdown.

 

Tellingly, that’s when the Babadook–a supernatural creature from a super-creepy children’s book–begins to terrorize them in their shadowy house.

 

the babadook gif

(Spoiler alert:  if you haven’t seen the film yet, stop reading here.)
.
From that point on, the film plays as a supernatural slasher flick. The Babadook possesses Amelia’s body and targets Sam. It/she stalks him with a butcher knife.
Or, is it the case that Amelia has simply lost her mind? If so, the story shifts from supernatural thriller to psychological thriller and becomes much more disturbing.
But the camera storytelling keeps us on the fence. It’s a classic presentation of Freud’s the uncanny:  we don’t know how to take Amelia’s violence–is she possessed or is she insane?
.
Rather than run away, Sam fights back. With his arsenal of homemade weapons, he pelts Amelia/Babadook with darts and bocce balls.
 the-babadook-Sam weapons

He slows her attack long enough to wrest her attention: “I know you don’t love me,” he shouts. “The Babadook won’t let you!”

It’s at that moment the film so movingly reveals the central metaphor: that Amelia’s grief at the loss of her husband poisons her relationship to her child. The Babadook represents her resentment. Resentment kills relationships.

At the risk of revealing too much, let’s just say Sam battles the Babadook to the end.

Cronus locked up

How to Choose a Great (And Not so Great) Bike Lock

When I bought a fancy bike last year, I felt I needed to upgrade my security for it. Holy cow, is there ever a swamp of options to wade through when choosing a bike lock. Cable locks. U-locks. Chains. Kryptonite. Onguard. Blackburn. Abus. And they’re all so different.

After many hours of research, I picked a very secure lock. Then immediately had buyer’s remorse. I wish someone had told me to consider weight and convenience. My purchase, a Kryptonite U-lock, model “New York Lock M-18WL,” for $120.  While very secure, at 6.5 lbs it’s a total pain to carry around. After a few months, I got tired of schlepping that monster everywhere and had to find another, lighter-weight lock.

Back to the drawing board!

Two basic design principles had originally led me to buy the New York Lock M-18: a narrow shackle and 16mm thickness (or greater). These two design features neuter the two most common attacks against U-locks.

1) Bottle jacks: Bike thieves can bust open nearly any U-lock using a twenty-dollar tool available at any hardware store called a bottle jack, as demonstrated in this video . . . (Darn, YouTube has taken down all videos of bottle jacks defeating U-locks.) That is, unless the shackle is too narrow to fit a bottle jack inside the “U”.  If the jack won’t fit, it’s useless against the lock. Here’s a photo of a bottle jack beginning to warp a U-lock shackle: (photo credit needed)

bottle jack attack

2) Bolt cutters: A shackle with a thickness of 16mm is too thick for the jaws of even the largest bolt cutters. Less than 16 mm can easily be cut by bolt cutters, like this:

The little brother of my New York Lock M-18, called the New York Fahgettaboudit Mini ($90), has both a narrow shackle and an 18mm thickness. And it’s lighter and smaller; its shackle is only 4 inches long, instead of 8 inches, making the NYF Mini only 4.55 pounds. I could have saved myself more research by just going with it. http://www.kryptonitelock.com/Pages/ProductInformation.aspx?PNumber=997986     

But that’s still heavy. Worse, an even bigger problem is its shackle is actually too small to be practical. It’s so small, people ride around with the NYF Mini stuffed in their back pockets. For portability, that’s a pretty great feature. However, the shackle is so narrow, it severely limits the ways in which one can lock up a bike. It can lock a bike frame to a bike rack, but without room for either of the wheels. Plus, if your frame tubing is oversized, as mine is, good luck using the NYF Mini on a thicker street pole (like a parking meter). It just won’t work. And the lock is too small to lock up just the rear wheel, as shown below with a larger lock: (photo credit needed)

bike lock proper

The Sweet Spot

I eventually found a U-lock by OnGuard, the Brute Mini ($70), which hits the sweet spot between strength and weight. At 16.8mm thickness, the Brute Mini is impervious to bolt cutter attack. Yet the lock weighs in at a svelte 3 lbs. The shackle is also about 15% larger than the NYF Mini. With just that much additional size, I rarely have difficulty locking up my bike. Yet the shackle is still too small to fit a bottle jack.  (See my photo at the top of this post. There’s no way to fit a bottle jack inside the shackle.)  http://onguardlock.com/products/u-locks/brute-mini-u-lock/

Bike Locks I Ruled Out

Lots of people use cable locks because they’re cheap and convenient. They’re lightweight and easy to stow. But against bolt cutters, they get snipped like ribbons.  “Steel-jacketed” cable locks are a little better because they’re fatter. But they’re better only to the extent that a thief would need a second tool to get through it: one tool to flatten or saw through the (very thin) outer steel jacket, and bolt cutters for the inner cable. See the outer jacket separated from its inner cable, below. (Photo credit:  http://lettershometoyou.wordpress.com/ )

sliced-cable-lock-stolen-bike-lettershometoyou

Case-hardened hex link chain might seem like a solid option, especially since it is marketed to motorcycle owners. But the thickest hex chain is only 14mm. Thus, a pair of 42-in. bolt cutters can quickly dispense with even a $150 chain, as seen here:

Plus, a three-foot length of 14mm hex chain will run about 10 pounds. And that’s not including the lock! There is a security chain manufacturer in the UK called Almax, which produces thicker, non-hex links. But, again, the weight. Such beasts were never meant to be carried on a bicycle. Maybe for locking up at home, but certainly not to carry on one’s daily commute.

In my research I came across the very cool TiGr Lock. Sadly, I found it just after its Kickstarter campaign had expired. Doh! Missed my chance to get one for $100. Now that they’re on the market, the 0.75-in. version is $165, and the 1.25-in. version is $220. http://tigrlock.com/ Wired Magazine reviewed the TiGr Lock as “deliver[ing] the holy grail of locks–strength and lightness…” The 1.25-in version is immune to bolt cutters, and weighs a mere 1.5 lbs. Be still my heart.

But I’m just not able to plunk down $220 for a bike lock. Maybe if I hadn’t already squandered so much on that $120 albatross, the New York Lock M-18.  Sigh.

(UPDATE: I spoke too soon in praising the TiGr Lock. Have a look at this video:

Granted, the TiGr Lock being cut in the video is the 0.75-in. model. But the bolt cutters snip that lock so easily, it’s hard to believe the wider version would make much difference. (The 1.25-in. model is wider, not thicker.)

Two Attacks NOT to Worry About

Ever heard of the liquid nitrogen attack? In bike thievery lore, a lock can be shattered if frozen with liquid nitrogen, then hit with a hammer. In the wild, liquid nitrogen is simply not a common threat. Here’s a discussion of it: http://www.creekcats.com/pnprice/bikelock.html

Also rare is the angle grinder attack. The first time I saw an angle grinder in action, my heart sank. An angle grinder can dispense with any lock listed here in 90 seconds, quicker with any lesser lock. Much quicker. The good news is they cause a scene. They throw a shower of sparks and shriek like a banshee:  https://www.youtube.com/watch?v=bphyY1pnjg8  To guard against an angle grinder attack, one simply needs to park one’s bike where 90 seconds of sparks and screeching noise would be unwise for the thief. (Photo credit needed.)

Final Notes

No matter what type of lock you use, there’s one security principle that undergirds all scenarios:  how long you leave your bike unattended. The longer a bike sits in one spot, the higher the chances it will catch the eye of a bike thief. Also, knowledge that the owner won’t return anytime soon puts the bike thief at ease. That’s the worst kind of bike thief: the brazen thief, the confident thief. Even if your bike is secured well, given unlimited time, bike thieves will take what they can. (Photo:  Luca Masters)

Surviving Wisconsin Winters, Part 2: Dry, Cracked Skin on Hands

Health

 

Ever get that dry cracked skin on your knuckles or at the side-edges of a fingertip? I can’t tell you how many different hand creams I’ve tried to prevent it in these Wisconsin winters. It’s a real problem. It’s not only the physical discomfort. It’s the anxiety of being out and about in the world with what are essentially open wounds. (Entrepreneurs shake a lot of hands!)

I’ve had to pull out the big guns. I’ve tried a couple of expensive, specialty products and some not so specialty home remedies. Turns out the best of the lot is also the cheapest. Namely, lip balm.

Lip_Balm_Beeswax_nocap (1).jpg

Chapstick, Burt’s Bees, Kiehl’s Facial Fuel, etc. — give any of them 36 hours with your cracked-skin convalescence, and they’ll put you on the road to epidermal ease. (Make sure you wash your hands before applying, or risk an infection.)

Also important, put away the liquid hand soaps ’til Springtime, especially the antibacterial ones. Get yourself a gentle bar soap with a lower pH.

What’s it gonna take?

That’s the question we’re all asking after the countless cyber attacks on the world’s most powerful corporations. The Sony Pictures hack got a lot of attention for the 47,000 embarrassing executive emails and celebrity Social Security numbers dumped onto the Internet. But check out this list of high-profile hacks and how many records were breached:

  • Michaels Stores, Inc. — 2 million
  • JP Morgan — 83 million
  • Home Depot — 109 million
  • Target — 110 million
  • eBay — 145 million
  • Adobe — 152 million
  • Court Ventures (Experian) — 200 million

We’re talking credit card data, home addresses, checking account numbers–everything an identity thief dreams of at night.

For this post I had planned on listing all the household-name companies hacked in recent years. But it would be way easier to list the handful that weren’t hacked. One prominent cyber security analyst claims 97% of all companies have had their servers broken into.

What’s it gonna take for them to do better?

Actually, that’s the wrong question. We now know the biggest, most powerful companies don’t have our backs regarding Internet security. We also know, by the sheer scale of these attacks, that we have all been touched by these crimes, if not directly, then via someone close to us.

So, the real question is, What’s it gonna take for us to take better care on our own initiative?

Ethical Wool?

Health

wool-305684_640

I’ve recently blogged about my newfound love of woolen activewear (the flipside of which is my move away from synthetic fabrics). Here’s an update to that post.

As a winter cyclist I’m amazed at the high-performance qualities of wool. But my attention has been drawn to the question of wool as an ethical product. Can one choose wool ethically?

Yes. Or at least wool can be relatively ethical, compared with the wool fiber industry of only a few years ago. Back then it was impossible for apparel manufacturers to fully trace the supply chain of raw wool. In other words, even if manufacturers wanted to offer garments made of ethical wool, the info did not exist for them to avoid “mulesed” wool. Mulesing is the horribly inhumane animal farming practice defined here.

Nowadays an industry initiative called Zque guarantees the supply of certified, non-mulesed wool. Patagonia, Ibex, and Smartwool now use Zque suppliers, exclusively. The manufacturer Icebreaker Merino has mounted a similar effort called BaaCode.

None of this completely resolves the question of wool as an ethical choice. There’s still the issue of animal cruelty in shearing operations, not to mention the bigger question mark of humane animal treatment in mass production, in general. But it is progress.

Password Managers, or Doing Passwords Right

Entrepreneurship, Media

Part II in a three-part series on personal online security. Parts I and III can be found here and here.

please don't steal this

Still Using Scraps of Paper?

Back when I was “storing” passwords via pen and paper, I had, what, twelve pages worth? Fifteen? Of course it’s impossible to memorize more than just a few passwords, which is why people duplicate, or reuse, passwords on multiple sites. Reusing passwords is the primary no-no of personal Internet security. Yet we all do it, we who keep passwords on paper.

The trouble is, when a reused password gets stolen, the thief has access to any site associated with it. This is the principal danger for most when caught up when a big company gets hacked.

Then there’s the problem of using easily remembered passwords for our most frequented sites. Your dog’s name, your child’s birthday. Now that’s secure! Use it for online banking or your most-used email account!

Our third most common failing is not changing passwords regularly. Really? All fifteen pages worth?

If your password-tracking system is stack of dog-eared, greasy pages in disintegrating manila folder, you’re essentially dangling your business checking account in front of cyber criminals and taunting them to take its contents.

The Best of the Best:  LastPass vs. 1Password

Enter: the password manager.

Here are the two password managers I have direct experience with: 1Password and LastPass. These two, along with KeePass, represent the best of the best.

Ten years ago I started out with 1Password. 1Password is one of the few top password managers that does not store your data in the cloud. 1Password is essentially an encryption program, but one dedicated to password management. It generates and organizes strong, unique passwords, all encrypted and stored locally on your hard drive.

What soured me on 1Password is its lack of cloud-sync. It’s greatest strength was also it’s biggest weakness.

Like a lot of entrepreneurs, I have a raft of devices float through my life every few years. Without cloud syncing, 1Password  limited my password “vault” to my main laptop, only. After a few months I bit the bullet and manually re-created a second password vault on my second laptop. That chore took hours.

1Password did offer syncing via Dropbox. Convenient, yes. But then you have to rely on Dropbox’s security, as well.

At that point I switched to LastPass. Yes, this switch was guided, admittedly, by convenience. How great it was to have all my passwords on all my devices! But LastPass also offers topflight security.

I was queasy at first about LastPass storing my data in the cloud. It took some time to get comfortable with their basic concept: LastPass servers don’t actually store passwords. They only store encryptions of passwords. That’s how they thwart any potential inside job (a.k.a., a LastPass employee stealing customer data).

How Long Is a Billion Billion Years?

The encryption also discourages cyber attacks from outsiders. With AES 256 bit technology, a hacker who cracks the LastPass servers would need at least a billion billion years to decrypt even a single password. That’s not a typo. A billion billion. (Here’s a discussion of these numbers.) Hear that? That’s the sound of hackers crossing LastPass off their hit list. (1Password also uses AES 256.)

Finally, decryption of the LastPass ciphers happens locally, on your device. In other words, your naked passwords never travel outside of your device. Plus, you are the only one who holds the key to the decryption. That key is what LastPass calls your Master Password. Hence, the name–your Master Password is the last password you ever have to memorize.

So, I remember one, and LastPass handles the other 179.

No matter which program you choose, you should make your Master Password long and strong. And change it three to five times each year. Rather than a pass-word, I use a pass-phrase.

Two Factor Authentication

We should also all be using 2 Factor Authentication (2FA) with our password manager. Even if my Master Password were stolen, say, by keylogger malware, the thief still couldn’t access my LastPass vault without my 2FA security key. I love having my USB security key on my keychain, which I can use to access LastPass on any laptop or desktop. For my Android needs, I use the Google Authenticator app (always on a separate device).

It’s heartening to learn that LastPass is popular at MIT.

Gore-Tex vs. eVent: Two Waterproof/Breathable Cycling Jackets Go Head-to-Head

Health, Writing

showers pass Elite 2-0

What I’m interested for this post is the waterproof/breathable (WP/BR) fabrics of two different jackets I own: Gore-Tex vs. eVent.

I’m actually not going to review the jackets, per se.  What I will do is save you all from the fatal mistake I’ve made, an honest mistake that has ruined one of these two jackets.

Pictured above is my Showers Pass Elite 2.0 jacket, $250 retail.  At the bottom you’ll find my Patagonia Super Alpine mountaineering jacket, $600 retail.  Very different market segments, I know.  The WP/BR laminate in the Patagonia is the high-end Gore-Tex Pro Shell, while that of the red, Showers Pass jacket is an unspecified, entry-level product from eVent.  So, not apples and apples.  I can’t offer up the definitive Gore-Tex vs. eVent head-to-head competition.

Or can I?

Both Gore-Tex and eVent fabrics are laminates, both using an active layer made of PTFE (polytetrafluoroethylene). The best known PTFE product is Teflon. The PTFE used in WP/BR fabrics is manufactured by stretching a PTFE solid to be a very thin, microporous membrane. The micropores are what make the membrane at once breathable yet waterproof. The micropores are too small to let in liquid water, such as rain or melted snow, yet large enough to allow moisture vapor to pass through, such as perspiration evaporating from your skin or baselayers.

The PTFE membrane must be protected from contamination. Contaminants such as skin oils and dirt will permanently clog unprotected micropores.  Just how to protect the PTFE layer is where Gore-Tex and eVent part ways.

  • Gore-Tex covers the PTFE membrane with a protective film of polyurethane (PU) on the interior side of the jacket.
  • Rather than covering the whole PTFE membrane, eVent uses a proprietary method to somehow coat the interior of each micropore with an oil/dirt resistant chemical.

Wet System vs.  Dry System

Gore-Tex is the so-called “wet system”: it vents perspiration only after vapor has collected as liquid on the inner surface of the jacket. As liquid, the moisture necessarily seeps through the PU film by basic diffusion, from the area of higher pressure (inside the jacket) to the area of lower pressure (the outside air). This diffusion forces the liquid water through the PTFE layer. So for Gore-Tex, venting is a two-step process: body moisture (vapor) must first condense on the inner surface. Only then can it diffuse through the membrane.

On the other hand, eVent is the “dry system”: sweat vapor vents “directly” through the membrane. It need not collect as liquid, first.  In that sense, eVent is the “more breathable” of the two products.  The two-step process of Gore-Tex venting definitely takes more time.

The problem with eVent—and this is essentially why I’m writing this post—is that its micropores are still vulnerable to contamination by skin oils and dirt. Yes, the micropores are treated with an oil- and dirt-resistant chemical. But get it dirty enough– i.e., clog the pores really badly—and the PTFE loses its breathability. Permanently.

Thus, eVent garments require laundering way more often than you’d think. We’re talking cycling garments, so, “regularly” means laundering after heavy use.  Read: every, or every other, hard ride. If you ride through the winter, this means washing the jacket two or three times a week.

Washing it often isn’t a terrible hassle. But as everyone knows, washing machines are hard on clothes. So we’re caught between a rock and a hard place. Care for this jacket properly, and shorten its lifespan. Or, launder it less, and risk clogging the micropores.

In my ignorance, I managed to do both types of damage. First, I simply didn’t know of the need for regular laundering. I treated my Showers Pass jacket like a jacket. I washed it about once every four weeks. Micropores? Pretty damn, well clogged. Breathability went to near zero. When I learned of my mistake, I began washing the jacket weekly. Just one Wisconsin cold season meant laundering the jacket probably twenty times. Some of the breathability returned (though, mostly not). All the washing totally destroyed the DWR coating on the jacket exterior. Now the jacket no longer sheds water. Rain and snow don’t get through to the inside, blocked by the PTFE layer. But they do saturate the outer fabric of the jacket, sapping warmth.

Conclusion

I love my Patagonia jacket, while my Showers Pass jacket makes me sad. The Showers Pass jacket no longer performs. I’m pretty angry that the care tag didn’t alert me to the need for special care. I only learned of it on the web, after the damage was done. I wonder what percentage of eVent users know they should wash an eVent jacket as if it’s a sweatshirt? I also wonder, if laundered as often as necessary, will an eVent jacket survive even a single season?

On the other hand, I’ll be wearing my Patagonia jacket for years to come. It seems completely unfazed by three winters of serious abuse. And Gore-Tex requires no special care. So I won’t be laundering it to death.
