Arc'teryx Atom SL Men's Insulated Jacket

The Arc'teryx Atom SL is the lightest insulated jacket in the Atom collection, built for mid-output mountain activities such as shoulder-season hikes and easy winter runs. Its recycled Coreloft™ Stretch insulation delivers targeted warmth to the core without restricting movement, while uninsulated sleeves and stretchy fleece-lined side panels increase breathability and make overhead motion easy.

The body and lining use Fortius™ Air 20 and recycled 20d nylon plain weave with FC0 DWR finish, both 88% nylon and 12% elastane, and the jacket is produced in a Fair Trade Certified facility with bluesign® approved materials.
