How Does ThinLine affect Saddle Movement?

Most visually notable is how much better the saddle, and therefore the rider, stays in close contact with the horse. When pads are moving, up, down, left, right, we can only imagine how much more challenging for the horse it is to have this instability they must carry.  ThinLine does an amazing job of keeping you close and connected to your horse.  Thousands of riders will tell you how their horses’ performance improves just by adding a ThinLine Pad.

Saddle Fitting Solutions:

Common Conformation issues, how to resolve saddle fit:

High or peaked wither:

Any ThinLine Western Shimmable pad or English
Shimmable Pad
will solve your problem. Horses with profoundly peaked withers also have a hollow point at the shoulder: Often the source of saddle fit troubles. TL Shimmable pads provide gullet and wither clearance. Add Front ThinLine Inserts and your saddle will rest properly at the withers with additional support for hollow areas.

Mutton Wither:

Saddles pitch, roll or slip forward? Non-Slip might be the first reason you purchase ThinLine but the noticeable improvement in comfort for your horse is what will really make you happy. We suggest a BASfelt barrel saddle fit padIC ThinLine.  Or any ThinLine pad without front shims.

Sway Back:

Bridging Shims are the answer. Stack them then remove layers as your horse develops stronger back muscles. To retain the good muscle on the top line you’ve developed continue using your ThinLine without the shims.  For more information see: Saddle Fitting the Sway Backed Horse. saddle fitting solutions the best saddle pad

Riser Pads:

If you need to lift the back (cantle) of your saddle adding a rear shim to a ThinLine saddle fit pad is your answer. With lift pads be sure you are protecting your horse at the wither shoulder and trapezoid muscles. ThinLine can do all this for you.
