Mountain Test Riding has shown the NEW INVINCIBLE CROC PAD to stay in place better than the Rider's Felt PROTECTOR pads. They run COOLER than other pads with the ELLIPTICAL center cut! The Faux Crocodile Leather wipes clean and will stay sharp looking for years. If you prefer a Felt upper, put that in the notes section while ordering. The Contoured ProTecTOR has a 5.5" Cutback in front & has a Center leather re-enforcement. LINER pads have a sewn marine vinyl center-strip. The Liner is cut exactly like the Protector & is easy to remove & wash. NEVER WASH YOUR PAD AGAIN: 3mm FELT or 1" FLEECE is against the horse when the Liner is used. The fleece version is $30.00 extra & takes serious break-in Riding. I send a Protector Pad & FELT Liner with every new saddle. The saddle then gets down around your horse much better. Note: 6 front and 4 rear, 1/4" balance shims come with all western PROTECTOR Pads.
