In terms of quality for money, the REI Co-op Magma 15 sleeping bags is some of our favorite. These bags on your wallet are ultra-light, ultra-comfortable, and much easier than most similar specs bag. Magma bags made our top pick list last season, and these new bags are also at the top of our 10 Best Sleeping Bags and Quilts list. This sleeping bag provides enough room for any person’s legs and foot areas. There are definitely less expensive options on the market, but with the Co-Op Magma 15, REI has given an excellent value for money.
