KühlerTM: The World’s First Handheld Human Heat Sink

The patent-pending KühlerTM device maximizes core temperature cooling.

When you train hard, your body overheats. When your body overheats, your performance rapidly declines. It is fundamental physics and biology; there is no supplement that will change that. The only way to enhance performance is to reduce core temperature. To effortlessly stay cooler, train harder, and recover faster, get KühlerTM.

No ice, no water, no effort.
