Abstract: Composite structures and methods are taught relating to temperature stabilizing saddle pads, horse blankets, saddle girths, saddle seat cushions, and saddles for protection and increased performance of horses and/or riders, among other similar products. The invention provides for products that stabilize the temperature of the horse and/or the rider by absorbing heat generated by the body of the horse and/or rider when the temperature exceeds a preset temperature appropriate for the product. In this process heat energy is absorbed through phase change, resulting in a constant temperature as long as there is material that has not changed phase.
