Barrel saddle pads are used for the smaller, round skirt barrel racing saddles and some trail saddles. The barrel pad gives the rider a bit more coverage than a traditional saddle pad. It is a nice option for smaller horses or horses that may not be used to a traditional saddle. As they are smaller in size, they won't cause your horse to overheat that quickly. They are made of a water repellent material and can be made of synthetic or natural fiber. They can be purchased in various sizes and shapes to fit most saddles.
