The "DOUBLE LINK STRAP" is a new type of harness-style strap with a unique three-dimensional cut designed by Kosuke Kadota JAW. *Trademark registration pending. Based on Kosuke Kadota JAW's own experience, it is designed to put less strain on the cervical vertebrae and allow more freedom in instrument positioning than conventional harness types. Furthermore, the assembly and packaging of the "DOUBLE LINK STRAP" was done by Kosuke Kadota of JAW himself. The V-shaped plate, snap hook, and blade (string) are made from SAX bird strap custom parts, but you can also replace them with other custom parts sold separately if you like! 【please note】 *The shape of the harness is designed to fit the physique of Kadota JAW Kosuke, and may not fit depending on gender, physique, or instrument used. *Color may fade or transfer.
