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 Arcteryx's 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.

*The Atom Heavyweight Hoody was previously the Atom AR Hoody.
