The Fleeceworks™ FXK Halfpad with Rolled Edge is designed with the patented FXK technology for comprehensive wither relief and protection from spinal pressure. FXK Technology acts a shock absorber with two cross-elastic bands catching any pressure before it can reach the sensitive spine and wither region. A dropped front has increased protection from pressure caused by the point of the tree. The specially designed cut offers closer contact under the rider's leg. Specially selected Australian Merino Sheepskin provides superior thermal balance and relief for sensitive pressure points. This pad is machine washable in Cold water. Lay flat to dry.
