Horse Saddle Pads What The Best Saddle Pad For My Older Horse?

What the best saddle pad for my older horse? - horse saddle pads

I'm going to ride my mare of 20 years frequently, and for Christmas I want to connect to your platform, the comfortable chair. I looked a little orthopedic pillows, and they seem so expensive! I was hoping someone could give me some advice first hand. I had hoped to spend $ 30 or $ 40. I just want to make sure the always the best for my price range. Thank you!
