Sidewinder Jacket Women's

Engineered for demanding big-mountain descent, the Arc'teryx FW26 Sidewinder Jacket redefines weather protection and ergonomic freedom for deep-powder pursuits. Built with rugged, breathable GORE-TEX PRO fabric, this shell features the iconic off-center asymmetrical front zipper designed to curve away from the face, eliminating chin abrasion during high-output movement. The articulated patterning and boxier silhouette accommodate low-profile midlayers without restricting reach, while a storm-ready helmet-compatible DropHood™ provides complete coverage without sacrificing peripheral vision. Vibrant contrast waterproofing details, a dedicated sleeve pass pocket, and generous high-volume hand pockets round out this bombproof fortress against harsh alpine conditions.
