Designed for multi day cold weather trips this bag has a balance of warmth to weight. Chevron shaped stitching insures that the down stays on top of the body and doesn’t shift down the sides of the bag during use. Filled with 800FP ethically sourced goose down and cut closer to the body for all the warmth but less weight when carried. Pertex Quantum outer fabric allows the down to fully loft while providing wind protection and remaining soft to the touch. Three quarter glow in the dark zip closure. Specs: Shell: 100% polymide, Lining: 100% Polymide, Filling: 90% goose down, 10% feather
