Light, packable and proven, the Atom LT – an Arc’teryx icon – is a performance warming layer for backcountry adventures, alpine ascents and downtown commutes. Refined for its next generation, we elevated its performance and extended its versatility. The Coreloft™ Compact 60 insulation retains heat when wet and withstands repeated packing and unpacking. The soft, durable Tyono™ 20 face fabric resists wind and weather, and stretch fleece side panels improve ventilation and freedom of movement.

Redesign includes an update to the cuff construction for easier on/off and layering, an updated material package for enhanced durability, updated fit, and a dope dyed liner.



Versatile synthetic insulated mid layers with a high degree of weather resistance.



High performance, minimalist design that is durable for its weight.
