The reins of the bridle attach to the bit and are then held by the rider and used to control speed and direction of the horse. There are many different types of reins available. Training reins have coloured sections to assist new riders with where to hold onto the rein. Rubber covered reins offer better grip than plain leather reins, some rubber covered reins are softer and more flexible than others. Half rubber reins come with rubber on the inside and are very popular as they offer more grip than plain leather reins but when riding it appears that you are riding in plain leather reins. Plain leather reins and plaited leather reins are typically used for dressage and showing.
