Cuirass is a white marking that appears on a Courser's chest and resembes an armored breastplate.
It is always present on the upper half of the chest, but can spread over the shoulders, neck and barrel.
Cuirass will never touch the mane or cross the topline. It will never touch the belly or "connect" behind the forelegs.
Scalloped edges and unnatural patterns and shapes are possible, but should not be so intricate as to resemble Filigree.
Though large cut-outs are possible, Cuirass will never have holes, spots, or disconnected areas.

Cuirass markings are always perfectly symmetrical.
