The soft Neoprene Thigh Harness adjusts to fit most thighs with Velcro® straps, and may be used in the shower. The harness works well with any flared-based attachment, not included. Wear the harness for use with a partner or strap the harness around a pillow for self-pleasure. Or get one for yourself and one for your partner, and ride each other all night long. One size fits most.
