Providing reliable warmth in an incredibly versatile package, the Arc’teryx Atom Heavyweight Hoodie (previously known as the Atom AR) is equally viable as a midlayer beneath your ski shell or as a standalone jacket. Updated with a revised fit, the Atom Heavyweight Hoodie still benefits from lightweight yet highly efficient Coreloft insulation and a DWR-treated Tyono 30 face fabric. It’s also equipped with an insulated, helmet-compatible hood so you can rock it on all your outdoor adventures be it snowboarding, mountaineering, hiking, camping, and beyond.
