Where to start? I bought this jacket in Utah for a season in Chamonix which means significant amounts of large vertical days (meaning large temperature/weather changes) and ski touring/alpinism. I do like the fit of the model, me being a medium, (5'9, 160 lbs, regular build), I didn't feel like a typical jackass in the ridiculous cuts of the previous stoic models. This year's model has the added length which is nice when freeriding in pow, seeming to keep the extra warm in and not interfering with pack straps.
But seriously, when I look for a real shell, I like to make a mental checklist ( I mean there are certain things a real shell just should do).
I'll start by listing them below:
Waterproof/Water Resistant: Ok I know it's only listed as 20K (maybe the stupidest rating system ever, I'd like to add). Here's my experience: after about two days of low-intensity riding, even days when the temperature was significantly below freezing and I experienced light snow, the jacket was absolutely soaked in the shoulders and sleeves. In summary, not waterproof at all once the DWR or whatever wears off (in two days).
Windproof: The second I stepped off into winds higher than 25 mph, I could feel wind tearing through every part of the coat as if I was wearing nothing. Okay, great.
Weight: Heavy compared to an eVent shell or something gore-tex and actually waterproof/wind resistant.
Fit: Good, as described above
Design: A pocket for every chinaman whose blood, sweat, and tears went into this over-engineered masterpiece. Other than that, good, except for the typically useless hood draws that re-open after 20 minutes of skiing.
Breathability: the one domain where this jacket excels. Maybe that's a result of its complete failure to block any wind whatsoever. It's nice while touring to be able to wear it zipped up and pretend that if there was any precip, that it would block it from reaching my under-layer.
Summary: a jacket that's great for skinning up to pole-line pass in anticipation of your big night out at the peruvian. Unfortunately if the weather actually turned foul, you would probably wouldn't make it back to your subi alive.
