Arcteryx Atom Jacket – Lightweight Synthetic Insulation

The Arcteryx Atom Jacket is a versatile insulation layer for active outdoor use. Its lightweight construction works beneath a shell in cold weather or on its own in milder conditions, balancing warmth with mobility.

Coreloft Compact 60 synthetic fill packs down easily and regains loft quickly. A soft Tyono 20 outer offers airflow, wind resistance and a water-repellent DWR finish. Performance stretch fleece side panels increase breathability and movement, though these more open areas can feel cooler when you stop or temperatures drop.

The No Slip Zip helps the front opening stay in place. Zipped handwarmer pockets and an internal security pocket provide storage, while an adjustable hem and stretch-knit wrist gaskets help retain heat.
