Bridle numbers are requried to be shown on both sides of the horse under new British Dressage and British Eventing Dressage rules.
This is a really smart addition to your competition kit. A luxury premium leather number holder for competitions. Adds a touch of class to any bridle.
New British Dressage Rules - All horses should now wear a number on both sides of bridle or saddlecloth – there will be a two point deduction for riders using only one number.
