The Two-Strap harness gets its name from the 2 straps that go around the woman's genitals. This unique design allows access to all her areas of pleasure and provides her with a penis. Designed to fit a woman with waist measurements up to 44.5 inches. Made of soft leather for the best in comfort. Designed for use with a dildo that that has a flared base. Comes with 3 rings: 1.75 inch diameter, 1.50 inch diameter and 1 inch diameter. Will fit most dildos up to 1.75 inches in diameter with the included rings, and up to 2.5 inches in diameter if you add a bigger ring. We like the way the buzz dildos work with this strap-on.
