Half pad with thick wool, elastic and gentle on your horse. Because the wool pad itself breathes, pores in the summer and heat can escape and tighten the pores in the winter to prevent heat from escaping. Please use this product for elderly horses with thin back muscles. This is a great tool to use for horse exercises that keep in contact with your back. If the fluffiness is disappeared, you can wash it by hand with warm water and wash sweaters.
