Queen 0°F

I bought a fitted sheet of Amazon the covers the megamat duo and have a Teton queen size sleeping bag that works great. I can keep it whole or separate into 2 halves 

Get a Teton queen sleeping bag and you'll be fine

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

I have the teton bags. I have the 0f and the 20f. I have used the 0f down to 17f and i was cold all night. I would add 20 degrees to those ratings to be comfortable but they work and do the job. Make sure you plan the temperature accordingly. This will make or break your trip. Dont forget an inflatable pad and a closed cell foam pad too, it adds to the warmth and comfort.

I also have a Teton 0F bag and it’s great. Used it earlier this month when it got down into the 40s at night. Wool socks and a hat make a huge difference too. I love that sleeping bag.

Teton 0 degree bag, it's big and heavy but it's very comfy and like 80$

The Teton sleeping bags are really warm and comfy.
