Cold nights outside demand maximum protection. Coleman's Peak1 Zero Degree Sleeping Bag can keep you warm even in frigid conditions. In addition to 650-fill power RDS-Certified Duck Down insulation, it has a slim silhouette, Thermolock draft tube, mummy shape, and neck baffle to keep warmth trapped inside. A sleeve in the bottom holds a sleeping pad in place so you don't roll off and onto the cold ground, the recycled 20D nylon ripstop shell with DWR and 40D nylon liner keeps moisture at bay, and the ZipPlow zipper design with webbing along the inside keeps the zipper from snagging. The entire thing stuffs into a compression sack to take up less room in your pack, while a mesh bag allows for ventilated storage at home.
