Coda Endless Promise Down Mummy Sleeping Bag

For $400 you have a few options, but I would recommend looking at the Nemo Disco bags. Super light, extra warm, and they are shaped for side sleepers. You can also use them with a custom Nemo liner to get an extra few degrees. I LOVE my Nemo bag. I bought 10° bag and use a liner. I’ve been comfy at and just below 0° many-a-night.

Usually when it’s cold out, like 30-10F out I tend to really bundle up and Take my wool blanket to add to my Nemo 10 degree sleeping bag. I always recommend ‘over dressing’ when it’s cold, because you can always strip down if it’s too hot.

have you looked at the nemo endless coda 10/20 bag? i got one in the mail to check out and its a super nice bag. i ended up going with their 20/30 quilt instead but if i were a bag person it would have been a yes for me.

As a warm sleeper I would absolutely die in a 15 degree bag if it's 30+ out. I would have to fully unzip it and then struggle to regulate temperature all night. The Nemo gills help a little but they do not help enough if you're a warm sleeper and it's 15 degrees over your bag rating. I have a Nemo 35 degree bag that I use and I've never been cold in it even though the comfort rating is 40. If it's 50+ degrees out it gets too hot. 35-50 is definitely the sweet spot for it. Personally, as long as you're not in dangerously cold conditions, I'd always go with a warmer bag and wear extra layers to bed or have a backup quilt to throw over it in case it actually gets too cold. I've had way more camping nights ruined from having a bag that's too hot than one that's too cold. You can always add layers but once you have to fully unzip your bag because it's too hot you're in a tricky place with temperature regulation for the night. If you're a hot sleeper do not buy a 15 degree bag if you're basically only camping above 30 degrees. I would be looking at a 35 and then also buying a cheap synthetic camp blanket as an extra layer when needed or an only layer for nights that are 50+

I like the Nemo sleeping bags that have the gills. You can open them when it's warmer and zip them up as the temperature drops. Works much better for me than just opening the side zipper, which I find let's too much heat out.

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.
