This one of a kind strap on harness features two heavy duty nylon shoulder straps that easily adjust to support the weight of most large hollow dildos, along with an adjustable nylon waist strap to fit most sizes. A durable metal O Ring has an internal diameter of 2.6 inches holds most 12 inch dongs in place when the action heats up, while nylon webbing thigh straps easily adjust to hold everything together. You can also change the metal O Ring with others from your collection to hold smaller sized dildos in place too. A Velcro strap wraps around the shaft of the dildo for extra support, and four straps help secure the metal O Ring around the base of the dildo. This item does not include a dildo.
