Microfiber lined collar prevents neck chafing during high intensity use

Previously known as the Atom AR hoody, the freshly revamped Atom Heavyweight Hoody is Arcteryxs 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.
