The Arc'teryx Gamma Lightweight Jacket in Black is built with Fortius 1.0 fabric — a stretchy, breathable softshell material that provides wind resistance and freedom of movement. Arc'teryx, founded in 1989 in North Vancouver, has become the gold standard for technical outdoor apparel, and the Gamma line sits within their softshell range — designed for high-output activities where breathability is as important as weather protection. The lightweight construction, dual chest zip pockets, stretchy cuffs, and adjustable drawcord hem deliver refined functionality.
