The KoldRush helmet cooling system has taken the principle of cooling your body with water and incorporated it into helmets. KoldRush uses a 24-ounce seat-mounted water reservoir along with an internal pump to drive the water up through a tube spraying your head with a refreshing pre-set amount of cold water. KoldRush is powered by eight AA batteries and the total system weighs 7.5 ounces.

To get a nice drench of cold water, all you need to do is press a button located on your handlebars. A concern of the product might be having an accident while your head is connected to the seat post. Inventor Scott Powers thought of this, and designed the tube release system to activate when minimal upward pressure is applied.
