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 45 Sleeping Bag to keep you comfortable around 45°F. 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. A snagless draft tube prevent air from sneaking in and fabric from catching.
