Adjustable Wither relief. This is a perfect option if you are going to use your saddle on horses with different wither relief needs. The size of the squares and velcro strap are slightly smaller now that we've learned that it does not need this large a size. If you are considering this option please watch the video.  If you use this incorrectly it can cause a pressure point. It is VERY important that the velcro panel is FLUSH WITH THE PAD at the back edge where it meets the spine.
New pics coming soon.
