I think the best you can do is the Professional’s Choice SMX HD Air Ride saddle pads. Make sure you get the Comfort Fit style because it has a much better cut for the withers. It is worth every penny and it comes in so many styles and patterns and prints. My trainer loves hers and the support is unbelieveable, the quality is amazing. I know I sound like a salesperson, but everyone I know with this pad loves it and the technology in it is phenomenal. The shock absorption and how it molds to fit your horse’s back without being overly thick or fluffy to interfere with anything is great and totally worth it.
