Side Sleepers Sleeping Bag

Are you crazy? I don't know, but I would love to find a side sleeping system. The best I've found so far is to use a quilt instead of a bag……

No joy on pads, though.

that I know the answer too, I'm certifiable.

I dunno… I'm a side sleeper and I'm using a very narrow mummy bag. Roll on my side, pull up my knees, it's all good. The bag moves with me. There's enough room to skew a leg off a bit if needed. And since the bag weighs 14 ounces, I'm betting you wouldn't find something much lighter.

I agree with Stephen.
It took me years to find it, but a quilt is side sleeping heaven. :)

As mentioned, if you move with the bag, your sleeping position is not really an issue. Of course if you really curl up into a ball, I find the knees and hips compress the insulation.
Also, moving with the bag negates any benefits from shifting down to the top in certain bags, thus, I prefer to roll inisde the bag.
This works well with larger volume bags, and as a side/stomach sleeper I have never had an issue. The one problem is that the hood can become useless if you roll over too far. I compensate by using a regular length bag (I'm 6'2") and bring along a seperate hood. I've seen down bags from decades past made with detached hoods for this purpose.
A quilt does work, but for me they simply are too drafty below freezing. However, I have used my Marmot Helium with most of the down shifted to the top and the hood from a down jacket while sleeping on my side in the teens.

I'm getting my first quilt. I think I'm going to work on a custom blue foam sleeping pad and see what I can come up with.
