The rules around what tack horses can wear for showjumping are designed to ensure that the competition is fair, and also that the horse is not being mistreated.
The most common types of nosebands are permitted for show jumping. These must be made from flat leather, although sheepskin padding is permitted at the intersection of a cross noseband.
So, as we have learned, choosing the right show jumping attire is essential to comply with the rules of the competition, especially when competing at a higher level.
