This is the most durable and reliable harness I’ve ever had! It’s made of nylon and even though it’s advertised as “one size fits most,” it fits up to a 60” to 65” waist, more than enough room to get the job done! It comes with four neoprene rubber O-rings, one already attached to the comfortable foam harness. It even comes with a 2.5” bullet to maximize pleasure for the user. It fits right into the little pocket on the inside of the harness, so you’ll both feel the passion and excitement of the Dominate Me Harness by Cloud 9 Novelties!
