The North Face Wawona Bed 35 Sleeping Bag basically effectively forms a double bag for couples or bed hogs. Rated down to 35F, it features recycled polyester fill for light and packable synthetic insulation with an abrasion-resistant shell and liner for long-term use. We like the wraparound footbox zipper-which lets us fully open the bag to lay it flat-and the bag's double capacity, which is perfect for sleeping on our large air mattress or on top of two sleeping pads with our partner.
