Big Agnes Blue Lake 25 Women's Sleeping Bag


Looking for the one bag to tackle everything from car camping with the family in the summer to spontaneous overnight adventures? The Big Agnes Blue Lake 25 Women's Sleeping Bag is the perfect blend of a lightweight sleeping bag combined with a durable insulation and nylon ripstop lining that will keep you comfortable no matter where you take it. Thanks to the women's specific mummy design and the Fireline™ Pro synthetic insulation, the Blue Lake is a highly compressible bag that traps and retains your body heat more efficiently to give you a better night's sleep.
