The adjustable wither relief is handy if you plan on using your bareback pad (NOT available for soft saddles due to how the top is designed) on horses with different wither relief needs. It can be adjusted from very low to very high, even higher than our standard for high/extra high. 
 
This is NOT available for use with soft saddles.
 
We do not advise using this with the handle option. If you have both the adjustable wither and the handle installed, changing the wither relief will change the distance the handle is from the pad.
