A saddle blanket is a blanket which is inserted under a saddle in order to absorb sweat, cushion the saddle, and protect the horse''s back. Saddle blankets have been used for millennia with all types of saddles. There are number of different modern designs. While a pad or blanket cannot take the place of a properly fitted saddle, pads with shims or blankets with a special design can partially compensate for minor fitting problems. The most blanket-like style is associated with the American-style western saddle. It is usually made of wool, cotton, or synthetic fabrics with similar characteristics. Some are a single thickness, others are made to be folded and used with a double thickness. When fitted under the saddle, they are approximately 35 inches square, though designs vary to fit horses of different sizes.
