As temperatures shift in the later Spring through Summer nights, you can stay comfortable and sleep soundly with the 2-in-1 design of the Kelty Tumbler 50°F/70°F Dual-Temperature Sleeping Bag. The poly-cotton lining is soft and comfortable to the touch, but with the compressible, lightweight CloudLoft insulation and unique dual-temperature design of the Kelty Tumbler, you can decide between a 50°F and 70°F temperature rating: insulation and the combined layered and quilt-through construction give the top side a 50°F rating for a bit more warmth; when temperatures rise, simply flip the bag over for 70°F-rated, breathable comfort on the bottom. Anti-snag design in the zipper draft tube unzips with ease for use as a blanket, or you can zip two bags together for a cozy couple’s bag. 50D Polyester Ripstop Shell. Fatman and Ribbon drawcords. Stuff sack included.
