Perfect for first-timers, the Beginner's Harness is made with a soft neoprene body that prevents chafing and feels great against your skin. The durable 4-way adjustable nylon straps feature easy plastic slides for the perfect fit on waists up to 44 inches and thighs up to 40 inches. Four metal snaps secure the 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 inches.
