Tory Vienna Sliding Side Reins Deluxe 5/8" sliding reins are bridle leather with snaps for easy on and off to be used with a training surcingle or saddle when lunging the horse. They are 76 inches from the breast center to the snap in the center adjustment, the center to girth loop is adjustable. Attached to girth with snap or girth loop, run the reins to rings on the surcingle or the saddle - the horse will adjust to the pressure of the side reins without the rider pulling on the mouth.
