Featuring strategically-placed down, the Women's Teton 15° Sleeping Bag is an exceptional pick for three-season trekking and backpacking. Its lofty 650-fill-power-down insulation and water-resistant Down Defender treatment will keep you warm and dry. After an epic day of adventuring, give your feet a rest in the roomy wrap-around footbox with a heater pocket for added comfort. Stretch tricot baffles help keep the fill in place, while the nautilus multi-baffle hood with a drawcord and full-length two-way zipper with a draft tube limit heat loss. If the interior gets too warm, use the fold-down secondary zipper to get some air. Tuck small items into the internal stash pocket for easy access.
