This incredibly comfortable Universal Breathable Harness is made with a breathable spandex body that prevents chafing and feels great against your skin. The soft-knit elastic waistband features an adjustable velcro strap to fit waists up to 44-inches while the adjustable thong-style back features metal snaps to fit most sizes. A built-in stretchy silicone O-Ring holds everything snug in place even when the action heats up.
