As the temperature in your microclimate rises, BioCool™ fabric absorbs excess heat and slows the rate at which your skin temperature rises. So you don’t get too hot.
When temperature rises, the body starts to sweat. BioCool™ accelerates the diffusion and evaporation of sweat, leading to a rapid drop of temperature.
As temperature falls, PCMs release heat, which slows the rate of cooling. It thus regulates your skin temperature in the comfort zone, providing you with a comfortable night’s sleep.
