The martingale bib is designed to support correct positioning and stable rein function as part of the martingale system. Multiple adjustment holes allow precise fitting, making it possible to position the bib correctly without interfering with the horse’s natural head movement. The design supports consistent use while maintaining comfort. The bib is equipped with openable martingale rings, allowing reins to be attached and removed without disassembly. For best function, it is recommended to use reins with larger martingale stoppers that fit the openable rings. Compatible with many breastplates and martingales on the market, the bib can be easily integrated into an existing setup.
