For those of you who don't like the feel of the center strap we have also designed the alternative (thigh strap version) of this harness. The thigh strap version has leg straps that go from the base of the harness front, around the back of the thigh, along the outer butt cheeks to meet the top of the harness front ring on each side. (Picture not shown) Then there is a waist strap that goes over the hips as shown. Sizes: Small = Approximately Sizes 0 - 8 Medium = Approximately Sizes 8 - 16 Large = Approximately Sizes 16 - 22 XLarge = Approximately Sizes XL - 3X Product Image Coming Soon.
