Supple S-shaped headpiece the latest Dyon innovation for the US Collection bridles. This S-shaped headpiece is an improvement on the model that you used to know. The difference? The S shape has been accentuated and the browband sits lower down on the headpiece so as not to hug the base of the ear one of the sensitive spots on your horses head. Accentuating the S shape also makes it possible to espouse the contour of the base of the ear without exerting pressure on it.
