When you need serious warmth without the bulk, the Arc'teryx Atom Heavyweight Hoody has you covered. It's the warmest version in the Atom series, packed with synthetic Coreloft insulation (60, 80, and 120 g/m² in different zones) that stays warm even when damp. The outer fabric is Tyono 30 with a DWR finish to shed light moisture and wind, while the PermeAir 20 panels under the arms boost breathability. The regular fit gives you room to layer, and the helmet-compatible StormHood adds extra protection. You get two hand pockets and an internal chest pocket, all with quiet, no-slip zippers. The cuffs are stretchy for easy layering, and the hem has a drawcord to seal out drafts. It's lightweight, packable, and made with sustainability in mind (bluesign® approved materials and dope-dyed fabrics). Whether you're hiking, skiing, or just facing a chilly day, this hoody delivers versatile, reliable warmth with Arc'teryx's signature quality. A go-to piece for active women in cold conditions.
