Strap down your partner and be in total control! The straight jacket keeps your partner restrained with belt style straps which are strategically located ( one at the neck, three that run across the back and two around the thighs.) Jacket also has three D-rings, one at the neck and one on each sleeve, for additional bondage positions. On top of all the great security, we have made the elbows more durable by applying extra leather to help prevent wear and tear.
