ca 1800’s Saddle Blanket
The terms saddle blanket, saddle pad (numnah) and saddle cloth refer to blankets, pads or fabrics inserted under a saddle. These are usually used to absorb sweat, cushion the saddle, and protect the horse's back. Saddle blankets have been used for many centuries with all types of saddles. Some are a single thickness, others are made to be folded and used with a double thickness.
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. When fitted under the saddle, they are approximately 35 inches (0.89 m) square, although designs vary to fit horses of different sizes.
