Celsius Regular, 0 Degree

I have [this](https://tetongear.com/products/celsius-0-f-sleeping-bag?srsltid=AfmBOooi222cLEe7peXRv9buoKHYBpuktxRJyTlij3OV0sE-nvq9F2pD) and it is sooooo comfy. Rated for 0 degrees F which is a survival rating, comfort is 20-30 degrees F, depending on how cold you run personally. If you run cold, it never hurts to add a wool blanket on top of the bag, that way it won’t itch you.

I will say I have teton 0° mummy sack and have slept down to 7° in my hammock (with underquilt and top quilt) and been totally comfortable 

Granted the underquilt is suppppper warm 

I have this bag (0F) and it's very comfortable. Just camped in Colorado at 8,200 feet, got down to high teens/low 20's, and I was toasty warm. I did not need a blanket, the bag was enough.

We use Teton Celsius 0F bags for camping in cooler temps - they come in 20F, 0F, and -25F versions. It looks like their regular mummy bags are also available in 0F if you don't want to shell out for the down version. They're on sale right now. With that and a properly rated pad, you should be comfy. You can always add blankets and clothing layers as well.

$125. Zero degree rectangular hunters sleeping bag. Dirt cheap, is warm and weighs a ton. Not for backpacking. Most sport & hunting stores have a version of this.

I've got a Teton Celsius (0 rating I think). It is comfy and pretty darn warm. I've used it a few nights in low 30's in t shirt and shorts and didn't get cold until really early in the morning. The only negative is that it is bulky, but if you not back packing that's really not an issue. I'm a bigger guy and its got plenty of room for me and has held up really well for the price.

i honestly dont know how much warm it provides but i like my s2s reactor bag liner. much better feel than my nylon quilt. but matched with my paria 15deg quilt, ive found it a good winter camp combo. that's with a nemo tensor extreme and ccf pad. also have a zero deg teton bag i use at hunting camp. thing is budget friendly ($100) bulky and wicked cozy. if space isnt concern, and budget is, its a good option. can look into bedrolls too. can throw certain setups in a snowbank and sleep cozy. have no product experience tho
