The Browning Klondike Sleeping Bag is a "heavy duty" oversized hooded rectangle bag. The Klondike uses Techloft Insulation which consists of multi-hole staple-length micro-denier fibers that have a siliconized finish for maximum insulation, loft, and compactness. The TechLoft insulation will keep you warm and toasty on those colder nights when you'd prefer to have more "wiggle room" than you get with your mummy bag. It uses 2-layer offset construction to eliminate cold spots. For transporting, Browning included webbing straps with quick release buckles that keep your "rolled-up bag" secure.FeaturesOversized hooded rectangleTech Loft+ insulationTwo-layer construction#10 separating zippersInsulated chest and zipper baffleRugged canvas outer fabric100% cotton flannel linerRoll-up straps
