Celsius Grand XXL -25° Sleeping Bag

Teton -25 degree is amazing.

I had just bought the -25 from Teton but the non canvas version. It is super warm, very comfy, a little too big to trap in heat especially by your feet. I would feel good if it was around 5-15 degrees out but I think you start getting pretty cold any lower.

I have a Teton Sports -32F and dang that thing is warm!! Toasty as can be, used it right at freezing with no issues.

The spouse and I have a pair of the -25 bags. Our reasoning was it is better to be over prepared than under. A person can always strip off a layer or unzip a side to cool off but if a situation ever calls for a lower temp bag you will be thankful you have it.

Yes. It isn't bad. We use them through the later summer through the spring. Just don't wear as many layers and kept the side unzipped.

Without spending a fortune, throw an emergency blanket under your sleeping bag. I like the Teton Celcius -25 degree. Then throw another emergency blanket over that and a wool blanket on top of that. Insulating your air mattress is key, as you lose a lot of heat out to the ground. Otherwise if you have a high R value air mattress that would work well, like a Sea to Summit ether light XR Pro. But no matter what a really low temp sleeping bag, insulation, and wool blanket or down bivy/quilt will keep you from freezing.

I have a -30 Teton, pad from my hest, and Teton cot. with temps often being 0-20F at night + heavy wind. I am with a large hunting group in a canvas tent with wood stove and propane heater. I used to use a couple bags and blankets that were rated for warmer weather but would still get cold even with all the layers.

Teton Celcius XXL, there is so much room in there. I'm a big dude and I roll in it easy.
