The Atom SL Hoody Women’s by Arc’teryx is a lightweight synthetic jacket made to bring reliable warmth on chilly days in the backcountry. Its slim, regular fit and hood design let you wear it as a standalone layer or pack it away when you’re on the move, making it a versatile piece for hiking, climbing or simply hanging around camp.
Built with Coreloft™ Compact 40 insulation, this hoody balances warmth with minimal bulk and weight. The combination of Torrent fabric panels (84% polyester, 16% elastane) and a durable Tyono™ 20D nylon outer shell gives you stretch where you need it and protection against abrasion. Inside, a 100% polyester mesh lining helps manage moisture and keeps the insulation lofting properly. Bluesign® certification means the materials are selected and produced with reduced environmental impact.
Coreloft™ Compact 40 is a synthetic insulation at 40 g/m² that mimics down’s loft but keeps trapping warmth even if it gets damp, so you stay comfortable in changing conditions. The Bluesign® label ensures each component meets strict standards for resource use and safety, giving you a more responsible choice without sacrificing performance.
