I have the HSS and am not fond of it. It is a good one to loan to friends who came to hunting camp without a harness. I use the Loggy Bayou harness and like it a lot. The SOP is nice too, but a little more bulky. I like to put my Loggy Bayou harness under my outer jacket and/or vest so I can layer up or take off layers when I need to without removing the vest. The harness is so slim there is no problem fitting outer clothing on top of it.
