Designed to be worn as a stand-alone garment or layered with other cold-weather apparel, the Arc'teryx LEAF Alpha Jacket Gen 2 is ideal for wet and cold environments. GORE-TEX BD450 3L 40d nylon ripstop and GORE-TEX L&F 3L 30d nylon form a protective shell that repels wind, rain, and snow in even the worst conditions. Featuring Arc'teryx's StowHood that virtually disappears into a zipper collar compartment and low-profiled internal and external pockets, the Arc'teryx LEAF Alpha Jacket Gen 2 is engineered to reduce bulk, while still providing the protection you need to get the job done.
