I just bought a Nemo bag based on thread comments a few days ago. It’s a hybrid shape with more room around the hips for side sleepers. It just came today. It’s PERFECT.

This. I hate mummy bags. I move too much in my sleep. My Nemo takes up a bit more space in my pack but it is so comfortable and a good night’s sleep, where I can fully roll around in my bag, is worth it. I will never go back to a mummy bag.

It might depend on how you're built, but I can get my leg up like that inside my Nemo bag. I have short legs, though.

I really wanted to love the Nemo, but if OP is a smaller person, Id warn they have too much dead space.

Nemo. Best sleeping bag I have used. On my second one.

I'm a side/stomach sleeper and love my Nemo sleeping bag. I have a synthetic one and it's quite bulky, but the down ones would compress better.

Ok so it’s important to know that the degree rating on bags is the survival rating. This is the “you probably won’t die of hypothermia, but you’re not gonna have a good time” rating. Rule of thumb is to add 10-15 degrees F to any bag rating for the comfort rating. Always err on the side of caution with colder temps. If you get warm, you just open the bag. Some bags even have vents (my Nemo bags do). There are some tricks to stay warm with a bag, but for high 20’s, get at least a 15 degree rated bag. And have your son bring some good under layers to sleep in as a caution.
