I would never buy a neoprene saddle pad. For the similar reason that JDI explained. I do have a pair of neoprene splint boots which I like. But, every time I get the chance, I take them off and hose them/ or just hose them while on the horse. I don't think that sand + sweat + tacky neoprene would be too fun on a horses legs for long. So I make sure to rinse often.
