The SMX® Air-Ride™ OrthoSport® provides the essential fit that both aged and more prominent withered horses need to achieve an optimum level of comfort. The OrthoSport® has a second layer of shock absorbing material strategically located in the dished out area behind the shoulders, creating an even saddle fit from front to back. This improved fit assists in the even distribution of pressure across the entire back providing maximum comfort for your horse. Additional layers of this same breathable, shock absorbent material are channeled down each side of the spine to relieve pressure from the spine and kidney area while allowing additional airflow along the horse's back.
