For the last several years, I have been using a SOP harness that I usually wear under my outer-wear(always when bowhunting). I have been considering a new HSS vest mainly because I don't like walking in the SOP. With the HSS, you can just buckle the leg straps without going around your legs for the walk in. If you do this with the SOP, the buckles keep coming undone or the strap slides back through(you probably have to have one to know what I'm talking about). Anyway, I have also noticed that the new HSS vests have rubber coated buckles and are of a slimmer fitting design. Anyone have one of the new ones? CD.
