This is a really versatile piece of gear. I have several and use them to compress sleeping bags and the dog bed. You can use the stuff sack the bags came in. As another reviewer noted, the straps can come out of the buckles, but that is easy to fix. The straps can also get wrapped up in a tangled mess if you're not careful.
