The hunter-jumper division is a branch of competitive horseback riding that is judged on the horse's performance, soundness and when indicated, conformation, suitability or manners. A "show hunter" is a horse that competes in this division. Show hunters, ideally, show many qualities that were rewarded in the fox hunting field such as manners, fluid movement, and correct jumping style. They are shown in hunt seat style tack, and are often of Warmblood or Thoroughbred type, though a hunter-style pony is also seen in youth classes. In the United States, show hunters are primarily exhibited over fences, with a few additional classes offered for horses shown in-hand or on the flat. In the United Kingdom, competition over fences is called "Working Hunter," and the term "Show Hunter" describes classes held on the flat.
