Jam 15

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

I can vouch for Nemo Equipment bags (I have 3 down ones and one synthetic for different temperature ranges). I can also vouch for Marmot down coats (for in-town use not for winter backpacking or camping) but I have never used a Marmot sleeping bag. My 3-season backpacking bag is a Nemo down 15F version that is probably 10 years old now and it is great except for in extreme heat and extreme cold at night. I have an old Eddie Bauer Flying Squirrel Sleeping Bag (modified with velcro) that I use for extreme heat and other Nemo down sleeping bags for winter backpacking. Nemo has a lifetime warranty on their equipment.

I love my down 15* Nemo bag. It's a huge warmth difference compared to my synthetic 25* Nemo.

I’ve used an EE 30° quilt below freezing with a Tensor Extreme and been fine. I’ve used a 15° Nemo Bag with a tensor elite above freezing and been cold. I am a believer in the sleeping pad makes the biggest difference solely based on my own personal experience.

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.
