The Sidewinder Jacket is Arc'teryx's women's-specific freeride shell, cut with a relaxed fit that leaves room for layering while keeping a clean, structured silhouette. Its 3L GORE-TEX ePE construction pairs a recycled nylon face with a softshell flannel backer, so the jacket stays waterproof, windproof and breathable while feeling comfortable against the skin.

The thermomoulded, curved Sidewinder centre-front zipper cups the collar in front of the chin for chafe-free storm protection, and a helmet-compatible StormHood, pit zippers, gusseted Velcro cuffs and a cinching hem let you seal out weather on the skin track and in the bootpack. Six pockets, including a sleeve pass pocket and internal mesh dump pockets, keep essentials organised, while a RECCO reflector aids search and rescue in emergency situations.
