The Blue Springs sleeping bags from Alps are a hooded mummy shaped bag with a tremendous weight-to-warmth ratio. This sleeping bag series is made with MicroX+ insulation which consists of multiple denier staple-length fibers that have a siliconized finish for maximum insulation, loft, and compactness. The hood and mummy shape helps seal in the warmth and the 35 degree option has a second zipper to leave the bag half open to vent some of the heat out if needed. This bag won't take up much space in your pack or weight you down for a backpacking or hiking trip. The Blue Springs bags come with a compression stuff sack and insulated zipper baffle.
Note: Total weights listed are for the bags only. Add 3 oz. for the standard stuff sack.
