The Cooldanna is a head and neck tie that is designed to keep you cool for hours. It stays cool with the use of hydrating crystals that are in the fabric.
The CoolDanna stays cool through the process of evaporative cooling, where water evaporates from the fabric surface, absorbing heat from your skin in the process and providing a cooling sensation. The water in the CoolDanna is designed to gradually evaporate over time, keeping you cool for a longer period.
The fluid that keeps the body cool is sweat.
