Very well built.

I have a medium and a large bag. In the almost three years that I've had them, the medium has continued to work well, but the large one seems to get a bigger and bigger rip every time I use it - and the rip started to form form very early in using it. I'm not sure what caused this, but I suspect poor quality stitching on the large one.

You can never have too many of these laying around. I originally bought to compress and pack my jacket and bibs in. The medium stuff sack doesn't quite fit both so I'll have to pick up a large. Not a big deal for I most certainly will find a different use for this stuff sack. It's light weight and tough.

I have a bigger sized compression sack which I use for a sleeping bag and it works great. The compression sack is durable and light weight. I bought the smaller one simply because I was impressed with the one I own and knew I would be able to utilize a smaller one.

I like this sack but I wish the straps were thicker. Also when you really synch it down you can see the threads start pull apart from the pressure . I have tried several and still prefer SeatoSummits
