Fairfax Classic Dressage saddles have three billets. The saddle fitter has the option to remove the third one if it is not needed, or simply tuck it into the keeper on the girth.

Classic Dressage Girthing

Begin with neutral position – 2nd and 3rd billet

If the saddle slips forward the saddle fitter will use the 1st and 3rd billet

NEVER girth using the 1st and 2nd billet together – it will cause saddle instability
