An Icon Evolves

July 29, 2020

For over a decade, the Atom LT Hoody has been an Arc‘teryx mainstay. Steeped in the alpine, this versatile jacket has warmed climbers, hikers, backcountry skiers and even downtown commuters. Redesigned for Fall 2020, the new Atom LT builds on its proven performance, updating and refining elements to further elevate its versatility as moves into the future.


• Textile package rebuilt from the bottom up for improved durability, thermal regulation, and sustainability

• New Coreloft™ Compact synthetic insulation is warm, light, and better resists packing out so performance lasts over time

• More streamlined fit layers easily and has a contemporary aesthetic that works on andoff the mountain


The updated Atom LT Hoody is more versatile than ever. Both women’s and men’s styles have a longer cut and updated style lines for a cleaner, more contemporary silhouette that works easily under layers. Materials and insulation have been upgraded as well. The new Tyono 20 face fabric is light, wind-resistant, and offers exceptional abrasion resistance or its weight. The stretch side panels now improve wear and resist pilling. The breathable Aequora AirPerm™ Liner helps regulate temperature during higher output and is coloured with a less resource-intensive dope-dye process.


Worn as a midlayer or standalone, the Atom LT Hoody is a versatile warming layer that performs across a range of conditions, activities and output levels. Its Coreloft™ Compact insulation retains its warmth even if wet, with loft retention that withstands years of packing and unpacking. And the Atom is designed to be packed. Light and compressible, it can be stowed in its own pocket or easily stuffed into a sleeve or its hood for travel. Insulation, face fabric, liner and side panels — even the cuffs — the Atom LT Hoody’s updates build on its legacy for the needs of the future.
