Arcteryx’s Beta SL jacket strips alpine protection down to its lightest form, without compromise. Crafted with next-gen GORE-TEX e PE, it’s waterproof, windproof, and PFC-free. The C-KNIT backer adds breathability and comfort, while pit zips and a helmet-ready Storm Hood keep things functional. A RECCO reflector adds subtle utility. Minimal, packable, and engineered for mountain realities, it’s performance gear with a quiet, technical edge. 100% Nylon Waterproof GORE-TEX e PE Shell Packable Windproof Adjustable Velcro® Cuffs RECCO® Reflector Helmet Compatible Storm Hood™ Internal Chest Pocket 2 Zip Hand Pockets Pit Zippers Style Code: X000010020-002592
