Sometimes referred to as a "breastcollar", breastplates are designed to prevent the harness saddle from slipping backwards.
The Buxton breastplate is the most commonly seen in modern harness racing, and named after Ohio-based trainer Dick Buxton, who was the first to use this design on Standardbreds in the early 1960's.
This is a set, comprising a breastplate and clip-on traces. The breastplate is lined with a PVC waffle padding, for both extra comfort and prevention from galling. The traces feature stainless steel snap hooks and multiple settings to ensure the correct fit. Both items are available for separate purchase.
