This bag is super compact and light and comes with a high quality stuff sack. Compact dimensions are roughly 11 inches by 6 inches. The bag is plenty long and has more room at the shoulders than other compact bags I've looked at. However, I'm a big guy (XXL shirts and jackets) and would love another 2 to 3 inches across for some more freedom in the shoulder area. The bag fits me, but just barely. I'm not a fan of mummy bags as I like to move alot when I sleep, especially on hard ground. I bought this bag for it's size, weight, and and temp rating. I live in Arizona and I'm an avid outdoorsman, bushcrafter, and hunter. I'm using this bag to throw in my day pack for survival situations and possibly summer and spring trips into the Coconino National Forest (7000 feet elevation). I would recommend this to anyone in the market for a compact light bag and as a "Plan B" for your vehicle or day pack for survival situations. I gave it a 4 instead of a 5 simply because I wish it had more shoulder room.
