Always warm, breathable and wind resistant, worn as a midlayer or standalone – the Atom Heavyweight Hoody is one of our most versatile insulation pieces. Its Coreloft™ synthetic insulation is efficient, effective and resilient. Mapped for optimal performance, it works well even if wet. The lightweight, wind resistant and water repellant Tyono™ 30 shell is treated for extra durability, and Permeair™ panels under the arms add ventilation. The insulated, helmet compatible hood adds warmth and protection.
