Jam 30

Since it’s temp controlled, I think any sleeping bag will work. I think it just depends on your budget. I have a Nemo jazz that I use for regular camping. When we sleep in the car- we just use a sheet and a blanket. Good luck op.

I have a Nemo Jam, which is shaped like the Disco. I'm a side sleeper and I absolutely love it. I don't think I could sleep in a mummy bag.

The Nemo spoon shaped bags, TR Boost or BA Torchlight are all nice and accommodating for flamingo type sleepers (I am one as well.) Also consider a quilt!

I’ve been backpacking with my Nemo 30 for about 4 years and I LOVE it. I’m a side sleeper and I toss and turn a lot and I find that it gives me (5’ 0”) plenty of room to move around without getting cold. On warmer nights, I just open the zip and get enough airflow to not overheat. It’s lightweight and packs down super well with the provided compressive bag. Generally speaking, I run warm, and have comfortably used this bag in temps well into the low 30s with wool base layers and not felt cold

i’m 5,3” and i have a women’s nemo bag that fits just right

I sleep like you and it’s been the bane of my backpacking experience for the last 40 or so years. A few years ago, my husband bought me a Nemo side sleeper sleeping bag for Christmas. I was a little skeptical, but it actually helps a lot. I can’t remember what it’s rated to. It’s definitely not for extremely cold nights, but I don’t know if there are options in that. For car camping one of the main things I do is carry a wider pad. That way when I pull my knee up into the side, it at least stays on the pad and isn’t on the cold hard ground. As someone else mentioned, I also keep some extra gear in a stuff sack, and use that underneath my knee, which helps for warmth and back comfort.
