The Arc'teryx Atom Hoody is a lightweight, highly packable insulated jacket designed for active outdoor use in cool to cold conditions. Featuring Coreloft™ synthetic insulation with horizontal quilting for consistent warmth and reduced bulk, it offers excellent thermal efficiency even when damp. The full-zip front with storm flap, adjustable hood, and articulated sleeves ensure mobility and weather protection. Two zippered hand pockets provide secure storage, while the brushed interior lining enhances comfort against skin. Constructed with durable yet soft face fabric, it resists abrasion and wind while maintaining breathability. Ideal for layering under shells or wearing as a standalone piece during hiking, climbing, urban commuting, or travel. Its minimalist aesthetic, subtle embroidered Arc'teryx logo on the chest, and refined gray tone make it versatile for both technical and casual settings. The jacket balances performance engineering with understated design—true to Arc'teryx’s reputation for functional elegance.
