Designed for maximum comfort the Perfect Fit Harness is made with soft nylon and Luv Touch materials that prevent chafing and feel great against the skin. The durable 4-way adjustable straps feature an easy-close clip and fit thighs up to 30 inches while the included waistband extension fits waists up to 68 in. Three metal snaps secure the metal O-Ring and hold everything in place even when the action heats up. The three included silicone O-Rings allow you to interchange a range of dildos with a diameter up to 2 in.
