This is a preview of a member exclusive premium article.

This series began with my article after the winter 2011 Outdoor Retailer Trade Show, where I commented on a long overdue advancement in waterproof-breathable fabric technologies. After nearly 30 years of market domination by Gore-Tex, we finally have several serious contenders that could capture a share of this high-end market. The challengers present some convincing claims and data on how well their fabrics perform in comparison to "traditional Gore-Tex." The stakes are high and the claims are lofty; are the competing technologies really better than Gore-Tex? Manufacturers would like you to believe that these jackets are "highly air-permeable," implying they yield comfort akin to air-conditioning. I simply couldn't resist, for this claim begs the questions: "Are these fabrics magical? Do they really deliver the level of comfort that they claim?" To find out, I tested and compared jackets made of the new fabrics under real world backpacking conditions.
