Very Difficult To Get Into
Hard to get into but should be warm. Probably should have got the one with no zippers

Offers Flexibility
I got this to add some degrees to my 15 degree sleeping bag for my outdoor camping experience in the Boundary Water in northern Minnesota in January. We were lucky in that it never got below 0 degrees but so glad I had it just in case it was needed. It did help in providing some extra security when my bag got a little wet from a leaking hot water bottle. I like that I have flexibility in keeping my feet bundled or kick them out. Very soft material. Used it with my Nemo spoon style sleeping bag.

Definitely Keeps Me A Little
Definitely keeps me a little warmer on those chilly nights and great so I’m not getting all my sweat and dirt inside of my sleeping bag. Very easy to wash and light to carry in my pack. Will definitely purchase again.

S2s Reactor Extreme
Very roomy and comfortable as expected. My only concern is using it with my air pad. Why would S2S use a sharp metal pull tab on zipper instead of fabric or pull cord. I rolled over and noticed the metal tab jabbing into my air pad. Thankfully I noticed and placed a piece of luko tape over metal tab. Will probably return or use it with closed cell pad.
