With no waistband, this harness is as minimal and functional as possible. Made specifically with the #1 Laboratory Model D STPs in mind, it has two fully adjustable elastic straps and a soft and durable vinyl center piece. The Slingshot sits comfortably low on the hips, securing the STP in place.
Note: The sizing for this harness is based on the circumference of your thigh — the same as a leg hole from a pair of briefs — not your waist. Adjustable from 16" to 24" in circumference. Machine washable; air dry.
