The NEMO Disco 15 Sleeping Bag is a game-changer for sleeping comfortably on our side while backpacking in frosty conditions. The innovative Spoon-shaped bag provides more room around our knees and elbows for side-sleeping while still packing down small for our long-distance backpacking trips. The Thermo Gill vents allow us to find the perfect amount of warmth on any trip, circulating out hot, stuffy air so we can get our beauty sleep. The hydrophobic down stays lofty as condensation builds in our tent, so we can enjoy consistent, reliable warmth the whole night through.
