I just purchased the HSS Pro Style, the mesh one. I ordered it directly from Hunter Safety Systems so as to insure the correct size. Most places just list M, L, XL, etc. and not the dimensions. I am very pleased with the set up. It is extremely easy to use. They also have a less expensive model that is basically the harness with a small vest to keep it in place for ease of use. The mesh one has 4 pockets and that is a big reason I chose it.
