It can be said that these animals are certainly one of the most archaic Presbytis species : they weigh about 7 kg,possess tail and hind legs longer than the body,have a sexual dimorphism just mentioned. The hair is metallic gray on the dorsal part of the body and whitish in the ventral part,with a white-white throat.The areas of bare skin (face,hands) are black,as well as the head.On the forehead,from the attachment of the hair of the head,there are two white stripes that depart in the shape of a "V" on the skullcap,which has a showy tuft of silvery fur.Around his eyes he has a gray-violet mask.
