Tired of the heat? Introducing a personal cooling system designed to cool your head and reduce risk of Heatstroke.
Our personal cooling system was designed to keep you comfortable in the heat. Consisting of a backpack equipped with ice-bricks and a powerful fan to cool and blast refreshing cold air onto the back of the neck and head. Additionally, an oval-shaped gel pack (a KOOLNUT) that fits snugly into a baseball cap or hat, which, when frozen, lowers head temperature instantly. By cooling the head, this innovative system optimizes body temperature regulation and reduces risk of heatstroke in hot environments. Whether you are working, exercising or simply enjoying the outdoors, stay cool, comfortable and safe, and beat the heat wherever you go.
Keep Kool with KOOLNUT
How it Works : A variable-speed 12V fan located at the base of the backpack pulls in warm air. The fan is surrounded by three ice bricks that, once frozen, cool the insulated compartment. As the fan propels air through this chilled space, the air cools and exits the top of the backpack. Cold air is directed onto the wearer’s back of the neck and head with immediate cooling effect. The fan has four selectable speeds (High, Medium, Low, and Idle) and is powered by a 20000mAh battery. The battery can run the 173CFM fan on High for 12 hours or at Idle speed for 24 hours; it can run the 250CFM fan on High for 10 hours or at Idle speed for 22 hours. The BLUE backpack features the smaller 173CFM fan, while the BLACK and YELLOW backpacks are equipped with the larger 250CFM fan. CFM stands for Cubic Feet per Minute and measures the air blowing capacity of a fan.

Your Hypothalamus...
The hypothalamus is your body’s temperature control system. Control its temperature to better regulate your body’s and lower the risk of heatstroke. Heatstroke is a life-threatening emergency that occurs when the body overheats to a core temperature of 104 degrees Fahrenheit (40 degrees Celsius) or higher. Common symptoms include confusion, agitation, slurred speech, irritability, delirium, seizures and coma. Located in the brain, the hypothalamus acts as the body’s thermostat to monitor internal temperature and initiate responses to keep it within a narrow range. When the body gets too hot, the hypothalamus triggers mechanisms like sweating and dilation of blood vessels to dissipate heat and cool your body down. Remembering that one of the largest areas of blood circulation is the brain, and blood flow is crucial for the delivery of oxygen and maintaining its vital functions; any disruption can have serious consequences. In summary, a well-regulated hypothalamus ensures that our body maintains a stable temperature, allowing our organs, circulatory system, and other vital functions to perform optimally.
