Familiarity: I've put it through the wringer
These pants are incredible. I've had them now for at least 5 or 6 years. There was a honeymoon period where I was gentle with them but I have been beating on them for a few years now and they are as reliable and solid as the day I got them. Totally bombproof ProShell engineering with extra strong material sewn into the knees, behind, and ankles. I wear these pants in all sorts of conditions, all year long. With waterproof full-length zips, they are lightweight and ventilated enough to wear on a humid rainy summer day, but heavily enough designed that, with a layer underneath, they offer warmth on the coldest days on the mountain. I appreciate the way they are cut too: they are sort of slim fitting around the legs; enough so that they look good and stay out of the way (unlike so many baggy ski pants). If you lay them on their side you can see that they are cut and sewn into a sort of aggressive stance: there is just enough extra room around the knees and ankles that they look trim but feel roomy. These pants are reliable and bombproof and I can't recommend them enough. As a disclaimer, I received them as a part of the MountainTec program in order to put them to the test and review them. I have. These pants are awesome.
