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.

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.

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!

We have this bag too! I run super cold and my husband is my heater lol. We put this sleeping bag in our roof top tent and I have loved it! It is comfy and big enough for 2 5ft11 people with extra wiggle room. We love it but it does take up space. Also for storage to keep it fluffy keep it out of the storage bag and only use the storage bag for transport.
