The LeMieux Self-Cooling Saddle Pads are made with the innovative 'Feel Cool' Ice material which has a cooling crystal kneaded into the weave. This is activated by moisture - the greater the moisture the greater the cooling effect! The crystals have incredible heat pick-up & transfer properties gradually absorbing and wicking sweat from the horse. Under extreme conditions, once dissipated a reverse rapid cooling effect is produced. The carbon mesh spine insert reduces any pressure over the wither & back and allows heat to rise and escape through the top of the pad. The inner lining is the same self-cooling fabric as the top side which is soft, friction free and ensures the whole pad breathes and wicks at the same level. An ideal pad for use in hot and humid conditions or for horses that generally sweat a lot during work.
