In East Tennessee, it very seldomly gets below 20 degrees at anytime, middle of night or anytime during the day. So I will be just fine with a bag rated for this weather and above. Plus, when in the field, and at FT. Lewis too, I sleep in full cold weather gear from underarmor and you would be amazed at how toasty I saty in my bag and bivvy.


Interesting thought on the winter bivvy and in the cold weather... I will get back and let you guys know when I get the bag and the bivvy and get the chance to get out in the woods and do some sleeping in my new sleeping system. Hooah.
