Perfect for first-timers, the Stay-Put Harness is made with a soft neoprene backside that prevents chafing and feels great against your skin, while the shiny patent outside is sleek and inviting. The durable 4-way adjustable nylon straps feature easy plastic slides for the perfect fit on waists up to 44-inches (112 cm) and thighs up to 40-inches (102 cm). The low-rise fit is super comfortable, while the four metal snaps secure the O-Ring and hold everything in place even when the action heats up. Three included silicone O-Rings allow you to interchange a range of dildos with a diameter up to 2-inches (5 cm).
