The Kalix Hooded Down Jacket features 700-fill down insulation for warmth and packability. It uses lightweight, breathable Pertex Quantum fabric with a durable Cordura overlay for longevity. A water-resistant treatment repels snow, while Heatseeker Eco insulation in the yoke provides warmth when wet. The adjustable hood blocks wind, and stretchy cuffs with an elastic hem prevent snow entry.
