A compressible stuff sack is disclosed, designed to be relatively easy to use and inexpensive to manufacture. The stuff sack includes a body made of flexible material with a main opening. A hands-free, one-way valve is provided on the sack which enables excess air to automatically escape from the sack when the sack is compressed. In one embodiment, the body is cylindrically-shaped and made of waterproof material. Attached to one end of the body is a bottom cap including an end plate with surrounding compression rings which are simultaneously welded over an opened end of the body. The opposite end of the body is opened and covered with a removable top cap. Four, spaced-apart compression straps are aligned longitudinally over the outside surface of the body and attached to the bottom and top caps. When the compression straps are shortened, the bottom and top caps are squeezed together to reduce the overall length of the sack and to compress the cargo.
