Olympian and Team Bronze Medalist for the US, Darren Chiacchia, recently switched to the Tota Comfort System, noting that the bridle’s sculpted cheek pieces and design seem to make it more comfortable for his horses:

There really seems to be immediate comfort for the horse in the first fitting, riders tend to think, when there are problems with a sensitive mouth, to check or change the bit first, but many times the poll pressure is the real culprit.  The contour of the Tota Comfort System allows the bridle to sit more comfortably on the cartilage of the face and poll, and especially for competitive horses and when you are using bits with different degrees of leverage, alleviating this pressure is key to creating a happy environment for the horse.
