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. You need the lightweight, PFC-free, mummy-style NanoWave 25 Sleeping Bag to keep you comfortable around 25°F. Synthetic SpiraFil High Loft Insulation will keep you warm even when things get wet. The full-length zipper provides easy ventilation. Two-way zippers plus a snagless draft tube prevent air from sneaking in and fabric from catching.
