CoolHead™. Anti-Heatstroke Cooling Insert.

The flexible, affordable, reusable CoolHead molds to your headwear and wards off high temperatures.

Made from high-grade PVA with evaporative properties, CoolHead is an affordable, absorbent, lightweight, reusable, and flexible insert that users can soak in cold water, and place under their hat or helmet to keep their heads 11 to 20 degrees Fahrenheit cooler for up to two hours. 

It was created by cyclist and innovator Sergejs Zelinskis to curb the number of preventable heat-related illnesses and deaths that take place worldwide each year, especially amongst athletes.

Without CoolHead exercising in the heat can prove fatal. The human has a normal body temperature of 98.6˚F (37˚C). To maintain this temperature without the help of warming or cooling devices, the surrounding environment needs to be at about 82˚F (28˚C). High environmental temperatures can be dangerous to your body. In the range of 90˚ and 105˚F (32˚ and 40˚C), you can experience heat cramps and exhaustion. When human body temperature gets above 104˚F, the most vulnerable tissues to heat strain in the body are nerve cells. And because the brain is comprised almost entirely of nerve cells, those are the most sensitive and vulnerable tissues. Blood flow to the skin increases, and that puts a strain on the heart and that's when heatstroke occurs.
