The most common bitless bridle, which is often used when horses have an injury in the mouth area or evade the rein aids. A hackamore acts on the poll, the sensitive bridge of the nose and the chin dimple. Single sided rein aids are not possible as the hackamore would catch an edge. The rider should be able to ride the horse with weight and shank aids through the turns when using a hackamore.
