- Hose’s langur is a relatively small and slender primate, characterized by a high forehead and a prominent forward-sloping crest in the center of the crown.
- Coat color varies between subspecies but is gray mainly on the back, white on the chest and stomach, and blackish on the feet and hands.
- The face is pink, with a distinctive black stripe marking each cheek.
- Babies are easy to tell apart as white with black lines down their backs and shoulders.
