Warm and breathable, wind and weather resistant, packable and durable. Worn as a cold weather midlayer or standalone during rest phases, the Atom AR 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.
