Nylon headstalls are made in the USA out of premium triple-ply nylon webbing. While nylon is not as resilient to abuse as beta it is quite economical and serviceable to provide years of use with proper care. All hardware is stainless steel and will not rust. Available in the following colors Black, Brown. Matching reins sold separately. Sizes available, Small ( Arabs and Ponies) Medium (Average Horse) Large (Warmbloods and large Thoroughbreds). There is plenty of adjustment in Dr. Cook Bitless Bridles, however if you would like to be certain your bridle will fit correctly (proper fit is important) we suggest you measure and use the sizing chart.
