Arc'teryx Atom SV Hoody 2027 – Mid Layer Jacket

Description

The Arc'teryx Atom SV Hoody is a synthetic insulated mid-layer built for serious cold-weather use — from frigid winter hikes to exposed ridgelines. Designed for alpinists and backcountry enthusiasts who need reliable warmth without bulk, it works equally well as a standalone piece or layered under a hardshell.

At its core, Coreloft™ synthetic insulation retains heat even when wet, while thermo-mapped full-length stretch side panels add breathability where you generate the most heat. The Tyono™ 30 micro ripstop face fabric blocks wind and resists abrasion, and a DWR finish free from intentionally added PFAS sheds light moisture. The StormHood™ is helmet-compatible and fully insulated, articulated patterning allows free movement, and an adjustable hem cord seals out drafts. Two hand pockets and an internal chest zip pocket round out the package.

Who It's For

This hoody is the right call for skiers, ski tourers, and mountaineers who spend time in cold, windy, or damp alpine environments. The stretch side panels make it breathable enough to keep moving without overheating, while the robust insulation and StormHood™ ensure you stay warm the moment you stop. It's built to layer cleanly under a shell, making it a dependable anchor piece in a technical layering system.

FAQ

• Can I wear the Atom SV Hoody under a hardshell? Yes — the regular fit and low-profile construction are specifically designed to layer smoothly under a shell jacket without restricting movement.
• Is the insulation effective in wet conditions? Yes. Coreloft™ synthetic insulation maintains its thermal performance even when damp, unlike most down fills.
