A good night's sleep is the foundation of an awesome outdoor adventure. Our white tail sleeping bag is designed with a rectangular cut, so you can stretch out or curl up with equal ease. It's packed with 5 lbs. of Poly-Therm hollow synthetic insulation to keep you warm down to 0°F, and will not lose insulating efficiency if it gets wet. We use a tough cotton canvas shell and cotton flannel liner to provide ultimate comfort and durability.
