This slim-fitting, technical down sleeping bag blends comfort and packability to bring you a sound night’s sleep, whether you’re high on the summit or deep in the backcountry, on foot or two wheels. It has a clever construction designed to maximize the performance of the 650FP European duck down and offer more heat for fewer grams. The L.O.F.T™ baffle technology reduces down migration and helps retain warmth while minimizing the amount of insulation required, which in turn slashes weight and pack size. Finished with a protective, windproof Pertex® Quantum fabric, this low-bulk bag is ideal for alpine missions in cold conditions.
