The EASY-CHANGE Gullet System is a revolution in convenience and comfort for horses and riders. It's a system developed to ensure that a saddle maintains the best fit for a horse by allowing riders to change a saddle's fit to suit a horse's changing shape. It allows you to alter the width of the head of your saddle to custom fit your horse's wither, in just a few minutes. This means you don't need to buy a saddle for every horse you own, and you don't need to buy a new saddle for a new horse. Available in six individual sizes.
