The Beta SL Jacket is Arc'teryx's lightest Beta shell, built for complete waterproof, windproof and breathable protection in a packable design. Its GORE-TEX ePE membrane is laminated to a bio-based nylon face and paired with a C-KNIT backer that keeps the fabric light, soft and comfortable against the skin.

A helmet-compatible StormHood provides full coverage without blocking vision, pit zippers let you vent on the move, and a RECCO reflector can aid search and rescue in emergencies. Two zippered hand pockets and an internal chest pocket carry essentials, while the fitted, articulated cut moves with the body over light layers or under an outer shell.
