The Arc'teryx Atom Hoody is a high-performance hybrid insulated jacket designed for active outdoor use. Featuring a lightweight, wind-resistant outer shell with horizontal quilted baffles filled with Coreloft™ synthetic insulation, it provides excellent warmth-to-weight ratio and retains heat even when damp. The hood is adjustable with drawcords, and the full-length YKK® Vislon® zipper ensures smooth operation and durability. Raglan sleeves enhance mobility, while two zippered hand pockets offer secure storage. A subtle embroidered Arc'teryx logo appears on the left chest, and the interior includes a soft brushed-back fabric for comfort against skin. Constructed with durable yet supple fabrics, this hoody excels in transitional weather—ideal for hiking, urban commuting, or layering under shells. Its minimalist aesthetic blends technical functionality with refined design, making it suitable for both outdoor adventures and casual daily wear. The clean white colorway enhances versatility and pairs effortlessly with layered outfits across seasons.
