Heritage Big and Tall Sleeping Bag

I remember seeing that bag in the LLBean catalog. Sadly, they followed Abercrombie and Filtch into the fashion industry, and many of their former, outdoor products no longer exist. I would look for a Coleman Heritage Big and Tall bag, and see if the zippers align. Two of those might connect as you desire. Mine keeps coming undone, so I would think it could interface with another. We use it open, flat, atop our mattresses. Then our mummy bags or a light blanket, or another, cheap rectangular bag... I get where you're coming from with this. Our REI mummy bags zip together, making me hot and her cold, so the conventional, rectangular sack allows a bit more freedom and temperature control. Today we picked up some sleeping bag liners from REI, and hope to have a more comfortable summer camping experience over the 4th.

If weight isn’t of a concern, just get a classic flannel-lined Coleman. They’re by and far the best. You can usually find them on sale at Big 5 or other sporting good stores

coleman makes a big and tall bag. nothing fancy but adequate for sure. been using mine for a few years now and I am very pleased with it. excellent for the price. i also have an Exped Megamat max to sleep on and it is fantastic. Definitely pricey but worth it. I also own a nice cot but never use it, the exped on the ground is very comfy without needing the extra weight and space of the cot. I have also used one of those tall queen sized inflatable air mattresses which sucks on its own…but if you get it very inflated and stiff and put a mattress topper on it, it can be very comfortable but takes up a lot of space.

Big Agnes echo park long/wide. I’m similar in size to you and love mine! If you can’t find one for a good price (they sell $200 new but I got mine $140 on sale) then go for a camping quilt or Coleman big and tall instead
