It's too small. When it showed up it was just about big enough and had enough "give" to it that I could awkwardly stick my butt into it, no back support. I'm not a big guy either, about 5'11. It must have been designed for a child or something. After owning it for about a month now, what was once overpacked has been reduced to a pathetic limpy bag that you wouldn't even think about trying to site on, a standard pillow has more fluff to it.
