Mammoth 0°F

We have a zero degrees Teton flannel lined double bag and love it. It's an absolute behemoth and takes up giant amounts of space in our car, and it's completely unsuitable for backpacking. We've been using it from 15 years. It's warm in winter and we've camped down to the high 20s. In summer it zips apart as a top and bottom so it's easy to throw off parts of it to cool down. We keep the two parts in separate stuff sacks because it's so unwieldy, but I'd highly recommend it. I've taken just the top to throw on as an oversize quilt on solo trips. I'll also say we are by no means petite people, and it fits us fine.

We have the 0 degree mammoth bag for fall and spring. It's beyond cozy!

I LOVE LOVE LOVE our [Teton Mammoth queen size 0F](https://tetongear.com/collections/mammoth-sleeping-bags/products/mammoth-0-f-double-sleeping-bag). It has a zip on each side. It is gigantic packed down though, just FYI if you're tight on space for hauling. It's very warm and very cozy.

I just got back from camping. I use a queen size Teton Sports Mammoth sleeping bag... just for myself. I will never go back!

Highly recommend the Teton Mammoth bag.

Omg we have this bag and the two separate stuff sacks is an incredible idea!! The bag is so huge but warm and cozy. We love it but it takes up a huge amount of space in one sack. Thanks for the idea!

Get a Teton queen sleeping bag and you'll be fine
