I have enjoyed the top quilt for many a Key West winter and just recently added the Vulcan Underquilt. Love it. Easy to set up.

Toasty!
So, I first used this in September after getting chilly the night before due to a breeze that I was not expecting. Night two, I wanted it there, in case I needed it. I am glad I did. After the day's heat left and a breeze picked up I work up cold. Pulled it up against me and. . . Well, it was exactly what I needed. I did buy a double ended stuff sack for both this and the hammock. Surprised that ENO does not ship with.
