The flannel interior is very soft and feels as familiar and homey as bed sheets. This feature of the sleeping bag attracts many customers to the product.

No-Snag Zippers

No-Snag Zippers

There are three zippers on the Mammoth Double 0-Degree sleeping bag. All of which are durable and designed not to snag. There is one zipper on the right side of the bag, one of the left side, and one on the bottom of the bag. The Teton Sports Mammoth Double Sleeping Bag is made for easy access and ventilation with the many zippers located on the product. The three anti-snag zippers allow for couples to adjust the temperature of their own side of the sleeping bag, without affecting their partner's. Best of all, the zippers are easy to open and close from both inside and outside the bag.

Pro Tip: When searching for the perfect sleeping bag for you, make it a priority to get a bag with functional zippers. The last think you want is for your zippers to snag, so read plenty of reviews before buying a sleeping bag. If most of the reviews report issues with the zippers, then pass on that product.


Teton Sports - Versatility

The Teton Sports Mammoth Sleeping Bag is not just a sleeping bag. It can easily come apart to make two large comforters. This feature allows the product to be versatile. When you are huddled around the campfire and want a thick blanket to wrap around yourself, you now have access to not just one, but two blankets! Instead of hopping into the sleeping bag, simply unzip the bag all around to make two quilts. Upon receiving this information, you may wonder if after you separate the bag you can make two individual sleeping bags. This cannot be done. The Mammon Sleeping Bag only functions are one large sleeping bag or two massive comforters.

What Travelers Are Saying About This Sleeping Bag

Let's start talking about what fellow travelers are saying about this sleeping bag. How does it stack up against similar products? For the most part, campers have spoken very highly about the Teton Sports Mammoth Double Sleeping Bag. For warmth, versatility, and quality, most travelers give this product between 4 and 5 stars. Travelers also love how the sleeping bag can unzip into two separate pieces. This feature allows for the campers to use the sleeping bag as a comforter when they desire extra warmth by the campfire. Plus, it allows for the bag to be washed with convenience.

Some complaints about this product have revolved around the hassle it is to repack the bag into its case. Unless you are an expert at folding and rolling sleeping bags, the process of stuffing it into the stuff sack can bring about some complications. It is also a very heavy sleeping bag to carry. At 16.5 pounds, this is not a sleeping bag fit for backpacking. However, for camping, this product has been known to live up to its 0-degree claims. Overall, we are pleasantly surprised by the Mammoth Double sleeping bag. For couples and families, this is a sleeping bag option to consider.
