Warm and breathable, wind and weather resistant, packable and durable. Worn as a cold weather midlayer or standalone during rest phases, the Atom Heavyweight Hoody is one of our most versatile insulation pieces. Its Coreloft™ synthetic insulation is efficient, effective and resilient. The light, wind resistant and water repellent Tyono™ 30 shell is treated for extra durability, and Permeair™ panels under the arms improve ventilation. The insulated helmet compatible hood adds warmth and protection.

Regular Fit - Our classic fit is cut comfortably throughout the chest, waist, hip, and thigh. It allows freedom of movement, provides shape, and layers comfortably over our insulation and midlayers. This model's fit has evolved. Before you check out, please make sure to reference our sizing chart to determine your correct size.
