Our ReactorPanel Numnahs and Saddle Pads are especially designed to fit over the panels on your ReactorPanel® saddle, with generous pockets with Velcro closure they are easy to take on and off and are machine washable using the recommended procedure, please see our Information page. It is advantageous to use our specially designed numnahs and saddle pads with your Panel saddle, because the panels themselves move independently with each side of the horse as he moves a traditional numnah or saddle pad can some times move underneath the panel and cause problems. For example the numnah can move downwards and pull tight across the wither if not pulled up into the gullet well enough and numnahs can sometimes work their way backwards. The ReactorPanel specially designed numnahs and saddlepads move with the panels as they are attached one on each side, leaving the gullet of the saddle completely open.
