The Dual Aspect Jacket is a fully PFC-free waterproof/breathable technical shell built for alpine climbing in the harshest conditions. This combination of full storm protection for the worst possible weather, a construction designed specifically for freedom of movement in the mountains, and a materials package free of perfluorinated chemicals is an important step forward in creating highly technical jackets with lower impacts on the environment.
