When space and weight are at a premium (think biking trips, kayak treks, and epic backpacking), you want a super packable, stuffable sleeping bag that'll fit into sterns, bike panniers, and bags. The lightweight, PFC-free, mummy-style Marmot Nanowave 50 Semi Rec Sleeping Bag is made to keep you comfortable around fifty degrees Fahrenheit. Synthetic SpiraFil High Loft Insulation will keep you warm even when things get wet. The full-length zipper wraps around the footbox for easy ventilation. Two-way zippers plus a snagless draft tube prevent air from sneaking in and fabric from catching.
