Atom Jacket (Women's)

Performing as midlayer and standalone across a broad range of activities and output levels, the iconic Atom is an Arc‘teryx mainstay. Over time, we have refined the design to elevate performance, improve durability and extend its versatility. Its Coreloft™ Compact insulation retains heat when wet and withstands repeated packing and unpacking. Light, soft and durable, the Tyono™ 20 face fabric resists wind and weather, and stretch fleece side panels improve ventilation and freedom of movement.

The Atom Jacket was previously the Atom LT Jacket.

Size and Fit Tips: Fitted Fit - This trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over our first layers. This model's fit has evolved.
