Skip the Supra. They're very cheaply made and won't last you long. HDR are quite decent though! If it will fit your horse, it would be a good option.I found them on kijiji so I cant use pictures directly from there idk why. but the synthetic one is black, supra, close contact, 17" seat 6 inch gullet, used but new condition.
the other one is leather, brown, HDR, close contact, 17" seat 6" gullet, used condition
