When warmth is the priority, the Atom SV Hoody delivers dependable insulation for cold, mid-output mountain missions. Built for frigid hikes, alpine adventures, and stormy conditions, it pairs breathable synthetic insulation with a wind-resistant shell to keep you warm without overheating when you’re on the move. Thermo-mapped Coreloft™ insulation focuses warmth where you need it most, while full-length stretch side panels enhance breathability during high-output climbs. The insulated StormHood™ seals in heat and fits comfortably under a helmet, making the Atom SV a versatile layer on its own or under a hardshell. Updated with a streamlined fit and PFAS-free DWR finish, it’s a reliable workhorse for winter layering.

ReBird program
The Arc'teryx ReBird program is a sustainability initiative focused on circularity, aiming to keep gear in use longer and reduce waste. It offers three main services: ReCare (repairs and maintenance), ReGear (trade-in and resale of used gear), and ReCut (upcycling materials into new products). It provides a way to extend the lifespan of products through, for example, Gore-Tex washing and, at times, offering 30% back in credit for traded-in items.
