Warm, slightly small with creatively deficient hoop/button closure

This sleeping bag is great at keeping you warm! I'm 5'9" and 195lbs, and it's a bit too narrow for me. I read about the latching system instead of a zipper before buying, and thought I'd try it. But honestly, it's not good. One latch already ripped off. Such a bad design. Luckily, I get warm easily, so I just leave it open a bit. Overall, I'd rate it a 6.5 out of 10.
