Big Agnes Lost Ranger UL 3N1 Sleeping Bag: 15F Down

Summer camping can lead to some Goldilocks-style discomfort: bag on way too hot bag unzipped suddenly we're getting blasted with cold midnight breeze. Luckily with the inspiration of the most versatile jackets out there the Lost Ranger UL 3N1 Sleeping Bag is just right. Two sleeping bags--one in a lofty lightweight rectangular shape and one mummy modeled after Big Agnes's Sidewinder bags--can be slept in together to offer cool-weather warmth when we need it and used apart for hot summer nights.
