My favorite dressage saddle I’ve ever owned was a County Competitor. Not only are Countys amazingly constructed and hold up forever, but it was super comfortable and fit my TB like a glove. It was one of those that I could throw on him with a baby pad, no half pads or other fit embellishments needed, and he went amazingly in it.
Regretfully, I sold it a few years ago when I was in a riding hiatus and needed the money. I wish I still had it!
