The Dy'on New English Hard Bib Martingale Attachment is made from stiff Dy'on leather with an embossed logo on the front.

It attaches to a breastplate or yoke with a stainless steel roller buckle, and the length is adjustable at the attachment point to provide the most effective fit.

Bib martingales have the same effect as running martingales in preventing the horse from raising his head excessively, but also prevents the problem of straps flapping around, which may distract the horse.
