Just to be clear. This bag is very comfortable. The big agnes sleep system is pretty cool although being attached to your pad takes some getting used to. The Fish Hawk specifically is rated to 30 degrees, but, I would not want to take it to that temp. At 50 degrees the other night I actually had a few cold spots. I attribute this mostly to the rectangular design and the edges of the non insula
