Built for high-output days across shifting conditions, the Arc’teryx Atom Jacket delivers versatile warmth without the bulk. Coreloft Compact insulation stays warm even when damp, while Tyono 20 fabric and breathable stretch-fleece side panels balance wind resistance with airflow during movement. Lightweight, compressible, and easy to layer, it works as a standalone on cool hikes or as a midlayer for skiing, touring, and cold-weather missions. Finished with a PFAS-free FC0 DWR coating, articulated fit, and practical pocketing, it’s a dependable all-season essential.
