Abstract
A progressive compressive zipper for attaching an at least partially compressible first component, such as a foam-core punching or training bag, to a second component, such as a weighted base. The first component has a first zipper half that encircles the first component near, but not adjacent to, the surface along which it connects to the second component and then angles downward toward the connecting surface, forming a ramp. The second component has a corresponding second zipper half attached to its connecting surface. A user may place the first component against the second component and zip the first zipper half and the second zipper half together, starting with the ramp. As the zipper is engaged, the first component is compressed against the second component due to the angle of the ramp.
