Western style rigging puts a lot of pressure in the front of the saddle, right behind the horse’s shoulder blades. This makes it hard for the horse or mule to move freely in the shoulder area. The double billet system on our custom endurance saddles also lies flat under the rider’s leg to eliminate chafing and irritation.Saddle fit for the horse is a huge concern for the endurance rider because endurance riding demands so much from the horse. No one wants to get pulled from a ride at a vet check due to saddle fit problems. Riding to finish, riding to win or riding for Best Condition, we take the worry out of fitting your equine athlete with the use of the patented . With an EQUImeasure mold it’s just like having the horse right in the shop.
