The 600-fill goose down in The North Face Womens Chrysalis 20 Degree Down Sleeping Bag isnt just from any old goose. This Eastern European goose down doesnt have stems, which means light, durable, and efficient insulation on chilly nights. A womens-specific shape in the Chrysalis Sleeping Bag eliminates unused space and cold spots, while Climashield prism pads help retain loft in areas that get a lot of use. The North Face Chrysaliss vaulted footbox gives your feet room to move when you turn on your side. Stash a watch or small light in the pocket for wake-up calls or late night bathroom trips.
