The Atom SL Hoody delivers lightweight versatility for alpine adventures. Engineered with stretch insulation concentrated in the core, this piece excels as a standalone layer during cool, damp conditions or pairs seamlessly under a shell jacket for enhanced warmth. Breathable construction and weather-resistant fabric keep you protected without bulk, while the streamlined sleeves and hood design maximize packability—ideal for trail runners and mountaineers who demand performance without compromise.
