Teton Sports Mammoth Sleeping Bag

Yes, the Mammoth is rated for 0°F. It achieves this through double-layer construction, full-width baffles, and draft tubes along the zippers and shoulders to prevent cold air from seeping in.

Absolutely. The zippers allow you to open the bag completely, transforming it into two separate camp comforters, which is great for warmer nights or lounging around the campsite.

Because it is a double sleeping bag designed for cold weather, it is substantial and best suited for car camping rather than backpacking. It includes an Oxford stuff sack, but you will need dedicated space in your vehicle for transport.

The bag features anti-snag, two-way zippers with metal pulls designed to minimize catching on the fabric. While no zipper is entirely immune to snags, this design is significantly more reliable than standard sleeping bag zippers.

The interior is lined with a soft-to-the-touch cotton flannel. It feels much more like bedding at home than the slick, synthetic nylon found in many technical sleeping bags.

Teton Sports offers a limited lifetime warranty that covers defects in materials and workmanship. It generally does not cover normal wear and tear or accidental damage like rips or burns.
