Mammoth +20ºF Sleeping Bag



  • Three-Side Zipper


When you want to cuddle while you camp, choose the TETON Sports Mammoth Sleeping Bag. It will give you the best night’s sleep with shoulder and zipper draft tubes, drawstrings at the shoulder and around the head, and double-layer construction with offset stitching to eliminate cold spots. It’s filled with SuperLoft Elite hollow fiber fill—all these features work together to keep you warm and comfortable anywhere you set up camp. If you get too warm, just unzip the bag a little at either corner or down the side. The bag comes apart in two massive quilts. Includes its own storage bag. Here’s a storage tip: Stuff the bag in, don’t try to roll it up and then put it back in the sack. Like all TETON Sports sleeping bags, the Mammoth Sleeping Bag comes with a Limited Lifetime Warranty.
