Feel like a superhero when you're hiking or climbing in the flexible, water-resistant Arc'teryx Women's Gamma Rock Pants. The Gammas are made with Arc'teryx's Fortius 1.0 softshell, which is reinforced at the knees and seat with a four-way stretch fabric to boost mobility and durability, so you don't have to worry about subjecting yourself to mutation-causing radiation when you wear them for radioactive gear-plugging and nuclear bolt clipping. The fit has been updated from previous versions, to be more trim and articulated, making the Gamma more comfortable on the wall and the approach.
