Always warm, breathable and wind resistant, worn as a midlayer or standalone – the Atom Heavyweight Hoody is one of Arc'teryx's 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. Updated with a revised fit.
Size and Fit Tips: Regular Fit - Arc'teryx's classic fit is cut comfortably throughout the chest, waist, hip, and thigh. It allows freedom of movement, provides shape, and layers comfortably over your first layers.
This model's fit has evolved. Before you check out, please make sure to reference our sizing chart to determine your correct size.
The Atom Heavyweight Hoody was previously the Atom AR Hoody.
