The HAAS Cavalier brush is made from a combination of white and grey horse mane and tail. The exterior boarder of the bristles are white and longer to sweep away dust and dirt and create a shine to the coat. The interior grey bristles and shorter and firmer which interlock with the horse's coat to clean the coat down to the skin. This promotes circulation, brings the natural oils of the coat to the surface and enhances the shine in which the exterior bristles have initiated. The strength and elasticity of the horse hair used in these brushes is unparalleled which makes this a superb and durable brush.
