The Kelty Supernova is seriously the Goldilocks of sleeping bags - not too tight, not too bulky, just perfect! Rated for 0°F temperatures, this down bag will keep you warm and cozy even on chilly nights in the backcountry. The roomy shape accommodates different body types and sleeping positions, so you're not feeling cramped like in those mummy bags. With 550 fill power down insulation, it provides excellent heat retention while packing down surprisingly small into the included stuff sack (about 17x9 inches when compressed). The anti-snag zipper with locking sliders is genius - no more fighting with stuck zippers in the middle of the night. What's really cool is you can zip two Supernovas together to create a cozy double sleeping bag perfect for couples or friends sharing a tent. Kelty even uses recycled materials in the shell and liner, so you're making an eco-friendly choice. Weighing just 4 pounds with dimensions of 76x33 inches in the regular size (fits up to 6 feet tall), it strikes the perfect balance between warmth, comfort, and packability. Whether you're car camping or backpacking, this bag delivers backcountry performance with car camping comfort. Your nights under the stars are about to get a whole lot more comfortable!
