German martingale (also known as Thiedemann reins) made of leather with an adjustable neck strap. Attachment to the girth is done via an adjustable girth loop with a snap hook. The narrow straps of the ring martingale are also adjustable and are secured with snap hooks. The leather end pieces (width 15 mm) of the rubber reins (width 21 mm) are equipped with buckles. The reins feature three D-rings sewn on the side: two on the leather end pieces and one on the rubber part. The narrow straps of the martingale pass through the rings of the bit and are attached to the D-rings of the reins with snap hooks. The fittings of the German martingale are made of chrome-plated brass with a beautiful silver shine. This dressage aid prevents the horse from raising its head too high or too far forward while riding.
