A horse blanket allowing freer movement of a horse in use, comprising a generally rectangular piece of material with a front edge, a rear edge and two side edges. The blanket is split, from each side edge to the center line thereof, into a front section and a rear section, the front and rear sections being connected together at the center line of the blanket to define a flexible joint therebetween, about which the blanket articulates. The flexible joint extends to a position to each side of the center line. The flexible joint is positioned, in use, at a location to the rear of the horse's withers where the pommel of a saddle would be properly positioned. The articulation of the blanket about the flexible joint facilitates up and down movements, side to side movements, as well as twisting movements of the front section relative to the rear section in response to movements of the horse.
