Sleep comfortably on overnight camping trips without adding bulk to your pack with the Phase 20 Sleeping Bag. You'll stay warm and dry in temps down to 20F, thanks to the lofty 850-fill-power-down insulation and water-resistant Down Defender treatment. After an epic day on the mountain, give your feet a rest in the roomy, wrap-around footbox. Smooth, curved baffles help keep the fill in place, while the nautilus multi-baffle hood, cinchable draft collar, and snagless draft tube limit heat loss. If the interior gets too warm, use the full-length, two-way zipper to get some air. Tuck small items into the internal stash pocket for easy access during the night.
