Atom Heavyweight Hoodie

Warm and breathable, wind and weather resistant, packable and durable.
Worn as a mid-layer in cold weather or on its own during rest phases, the Atom Heavyweight Hoody is one of our most versatile insulation pieces. Its Coreloft™ synthetic insulation is high-performing, efficient, and resilient. The lightweight, wind-resistant, and water-repellent Tyono™ 30 shell is treated for added durability, and Permeair™ underarm panels enhance ventilation. The helmet-compatible insulated hood adds warmth and protection.
