Arc'teryx Beta SL Jacket - Men's

Fast-moving missions in unpredictable weather call for a shell that won’t weigh you down or let you down. The Beta SL is the lightest jacket in the Beta line, designed for high-output days when space and grams matter. It delivers waterproof and windproof protection with a breathable feel, thanks to Arc’teryx’s next-gen GORE-TEX ePE membrane. Whether you’re climbing into sudden mountain squalls or hiking through shoulder-season storms, it keeps the elements out and packs down small when the skies clear.
