Leather Thiedemann reins with an adjustable neck strap and an adjustable girth loop with a detachable carabiner for attachment to the girth. The narrow straps of the martingale are also adjustable and fitted with carabiners. The rubber rein (21mm wide) has leather ends (15mm wide) with buckle closures. This rein has three D-rings on both sides: two on the leather ends and one on the rubber part. The narrow martingale straps are passed through the bit rings and attached to the D-rings of the reins with the carabiners. The Thiedemann reins are fitted with shiny, silver-coloured fittings made of chrome-plated brass. The Thiedemann rein ensures that the horse cannot raise its head too far and/or forward while riding.
