bodyjoys.co.uk: Featuring a heavy-duty vinyl strap-on harness that lets you play securely, the fit will improve with every use. The form-fitting thong and waist straps are fully adjustable to fit up to a 52-inch waist, with metal belt buckles and Velcro straps to keep everything in place. To keep the harness in good shape, gently spot clean with toy cleaner and warm water and lay it flat to dry.
