You'll stay warm and dry 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.
