Worked out great for me in my hammock. I used the Big Agnes Air Core pad (normal rectangle size) with another closed cell pad together. There was room in the sleeve to place both, this is necessary for cold weather camping in a hammock. I also tried the bag in a tent, and you cannot go wrongno more slipping off of your sleeping pad. The Bag is wonderful. Plenty of room for me to toss and turn. I did not feel cramped and plenty of toe box area. Most important was the hip and shoulder area, I had more than enough room. I would recommend this bag to anyone who hates a mummy bag.
I also used this bag, like a quilt and it worked out great. Anyone who is larger in frame will find this bag very comfortable, and well made with all the extras!
