The Atom Jacket, super lightweight warmth Performing as a mid-layer and a standalone jacket across various activities and output levels, the iconic Arc’teryx Men's Atom Jacket is here to stay. Over time, the design has been refined to elevate performance, improve durability and extend its versatility on and off the slopes. The Arc’teryx Men's Atom Jacket’s Coreloft™ Compact insulation retains heat when wet and can withstand repeated packing and unpacking, making it the perfect layering piece year-round. Light, soft and durable Tyono™ 20 face fabric resists wind and weather, and stretch fleece side panels grant excellent ventilation and freedom of movement. The Arc’teryx Atom is a fitted fit, staying close to the body throughout the chest, waist, hip and thigh to remain low profile while fitting comfortably over base layers. You can’t go wrong wearing this in the village or chucking it under a shell.
