Stay warm in your Coleman Oak Point Cool Weather Sleeping Bag, even when the temperature dips to 30° F. Inside the bag, the specially-designed, patented zipper system plows fabric away from the zippers to avoid snags, and Fiberlock Construction prevents Coletherm Insulation from shifting-extending the life of your sleeping bag. When youre ready to pack up, the patented Roll Control System keeps the bag in place for easier rolling and the QuickCord no tie patented packing system makes storage a cinch. The big and tall 39 in. x 81 in. bag fits heights up to 6 ft. 4 in. and is machine washable, with a polyester cover and soft cotton flannel lining. It also comes with a 5-year limited warranty.
