Eh... it was okay
March 26, 2012

It is very difficult to get into since it's only like a 1/4 zip on the left side. Bad when I have a right hand zip bag :( I slept under starry skies, no moisture, zipped it up most of the way and I woke 2hrs later to so much water on the inside of the bag I was afraid it was going to start losing warmth. I slept the rest of the night with it unzipped.

Cons: Bad design, Low performance
