Atom Jacket Women's is a breathable midlayer jacket designed for trail and hiking, built as a hybrid-insulated layer that provides reliable warmth and manages heat on the move.
Versatile synthetic insulated mid layers with a high degree of weather resistance.
Man-made insulation with quick dry times, durability and retains warmth when damp.
For trail and hiking systems, pair it with a women’s shell jacket and a beanie .
The Atom is the ultimate outdoor kit essential, delivering reliable, breathable warmth for chilly alpine starts and unexpected summit squalls. Built with lightweight Coreloft insulation that won't pack out (even after years of wear) and stretchy fleece side panels, it traps and dumps heat strategically. Slide it under a hardshell for a clutch layering system that'll keep you warm, even if it gets wet.
What's been updated: Updated with recycled Coreloft™ insulation and DWR (Durable Water Repellent) free from intentionally added PFAS.

Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.
Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
