    Comments about Outdoor Research Ultralight Compression Sack:

    4 straps, but 2 are buckles. This is great for not fussing with opening and closing the sack. Set it apart from others. The fact that it contains its own stuff sack is also key for throwing it in your bag. 10L size fits my North Face Mercurial 1S sleeping bag with a bit of room to spare. Packs down very small. Purchased this over other brands, such as Sea to Summit. Smelled like fish when it came out of the package though?
