Just purchased a 40F burrow
I finally sold one of my down sleeping bags, and now i have a 40F burrow on the way. Woohoo! Now i will have a 0F and 40f burrow. When it starts getting below freezing I will just switch to my 0F. I used my 0F this year in temps up to low 30s and it worked fine, although some venting was required.
I love me some hammock gear!
