Arc'teryx Atom SL Jacket

The Arc'teryx Atom SL Jacket is a superlight insulated mid layer designed for active mountain use. Its recycled stretch synthetic insulation delivers targeted warmth through the core, while uninsulated sleeves and fleece-lined stretch side panels support unrestricted movement and improved ventilation.

Built for hikers and well suited to runners, skiers, athletes and mountain guides, it balances lightweight packability with abrasion resistance and weather resistance. The breathable construction, articulated patterning, moisture-resistant outer fabric and adjustable hem make it a versatile choice for shoulder-season adventures and easy winter efforts.
