Evergreen 20˚F Mammoth Double Sleeping Bag
At TETON, we never tire of creating incredible outdoor gear with the best features, the highest quality, and a great price. Our latest example is the TETON Sports Evergreen Sleeping Bag. With a cozy cotton flannel lining, lightweight polycotton faux-canvas shell, and room for two, the Evergreen Mammoth is the right bag for car, van, and cabin camping. And maybe the best part is unzipping into two camp blankets -- or it's probably the unbelievable price for such a high-quality sleeping bag. It’s what we do.
