Leather side reins (19 mm) with long rubbers which allow your horse to move more freely as the rein gives way when your horse moves. The closures are freely adjustable and fitted with buckle closure. The snap hooks are attached to the bit rings. The side rein is fitted with stainless steel fittings. The side rein serves to improve a horse's balance vertically or horizontally and is used to teach the horse to decontract and find balance in the lateral bend of its body. The side rein can be used while riding and longeing.
