Fahrenheit Mammoth +20ºF Sleeping Bag




When you want to cuddle while you camp, choose the TETON Sports Fahrenheit Mammoth Sleeping Bag. You’ll be warm, comfortable, and have plenty of room for two. It is built to last a lifetime. The 100% cotton flannel lining feels like soft bed sheets, zipper and shoulder draft tubes keep the cold air out, and offset seams distribute our SuperLoft Elite fill evenly to eliminate chilly spots. Mummy-style hood keeps your head warm and off the ground. The Fahrenheit Mammoth has three no-snag, self-repairing zippers that open on either side or the bottom so you can adjust ventilation or enjoy two giant comforters. Comes with a free stuff sack. When the time comes be sure to stuff the bag into its compression sack, don’t try to roll it up and then put it back in the sack. Like all TETON Sports sleeping bags, the Fahrenheit Mammoth Sleeping Bag comes with a Limited Lifetime Warranty.
