The Dial MaxCool aspen pad is a type of cooling pad made from natural aspen wood fibers that are cross-laminated and glued together to form a thick pad. It has a honeycomb-like design that maximizes the surface area and allows for efficient water and air flow, which increases cooling efficiency. Additionally, it features a grid of channels that hold the water and allow it to evaporate efficiently, which further cools the air passing through the pad.
