The Double S Calf Collar was designed to decrease potential stress to the calf while being roped. The collar is black and features elastic cords and an adjustable nylon-webbing strap. It has a high-density padded neck and chest area to dissipate stress that may be experienced during the run. It does not interfere with roping or tying and is considered to be more humane. This is part of Stran Smith’s Double S line. One size fits most.
