Previously known as the Atom AR hoody, the freshly revamped Atom Heavyweight Hoody is Arc’teryx’s warmest option in their iconic Atom series. Ideal for use as a mid-layer or as a standalone piece in dry weather, it combines a synthetic Corefloft fill with a moisture-resistant shell that means despite its weight, it will dry quickly and maintain warmth even when wet. Rounded out with an insulated, helmet-compatible hood, Permeair side panels for ventilation, and stretch-woven cuffs.
