Perfect for first-timers the Beginners 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 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.
