The Big Agnes Women's Roxy Ann 15 Sleeping Bag mixes lightweight loft with weather protective capability for camping or backpacking in nasty conditions. DownTek treats the lofty down insulation with water resistant protection to retain its loft and warmth in rainy weather and moisture riddled environments. Insotect Flow Construction optimizes insulation by strategically placing vertical chambers with Flow Gates to minimize shifting and to ensure warmth where you need it most. For a roomy, rectangular shaped bag, the Roxy Ann is surprisingly light and compressible for backpacking trips. Big Agnes also equipped this bag with a draft tube around the hood and a full length zipper to keep brisk air at bay. Internal loops let you attach separate liners for extra comfort, and there are pockets for pillows and car keys. Since Big Agnes doesn't insulate the bottom of bags, be sure to pair this sleeping bag with a 20in sleeping pad.
