I've only used this bag for a couple of nights on one trip, but it was great. I've had a Big Agnes pad for a couple of years, but this is the first Big Agnes bag I've had to go with it. The little bit of extra room from the square mummy shape is great and worth the little bit of extra weight and space for me. I do wish this bag would come with a compression sack instead of just a stuff sack. Just a couple of lightweight straps sewn into the stuff sack would be great. The zipper snagged a couple of times, but as long as you're somewhat careful it's not bad. I'm not sure there's any way to completely avoid it on any sleeping bag. And for reference, I'm 6'2" and 215lbs and have plenty of room in the long. Now to find a good lightweight compression sack...
