Merging the best of history with the best of new technology to create the Diamond Line Saddle Pad. Riders across all disciplines know and value Diamond Wool for their quality, natural wool saddle pads. ThinLine is regarded as the best in back protection and performance-enhancing equestrian products in the USA.

These Western endurance saddle pads work for a wide range of saddles.  Western, Endurance, and Treeless Saddles fit well on this pad. Just double-check the measurements of your saddle to our sizes. Our Diamond Line Endurance Felt pad is 1/2″ thick and made with the highest quality wool felt. This pad features an excellent wither profile and has a contoured spine.

The Diamond Line Wool Saddle Pads are also a Pocket Correction Pad.

Full saddle fitting shims are available when you select your pad size.  These may be used as-is to double your protection or trimmed to create a pair of front, bridging, and rear shims to adjust your saddle fit.

    I just bought a TW ranch saddle, which requires a thinner pad. I love Diamond Wool products so I decided to try this duo between Thin Line and Diamond Wool. I’m more than impressed! It is easy to lift up in the front for wither clearance and conforms to my horses body. It’s just as good as my Diamond Wool pads I have used with other saddles. You won’t be disappointed with this purchase.

    Hi!  Actually, any of our pads will work well for horses with muscle atrophy. One of the gifts of ThinLine is that the horses actually move up into the saddle.  If you use our shims (these are located just below every saddle pad selection) you simply cut the shims, place them in the pocket under the ThinLine, fill the gap and let the horse develop better muscle tone.

    A HI. A solid brushing. Then you can hose it off. Use any sheepskin wash if you need soap then just let it hang to dry, out of the sun!
