UV protection index UPF50 [Cooling sensation (special menthol)] Menthol stimulates and activates the M8 sensor, one of the nine types of temperature sensors in human skin, sending a continuous signal of "cold" to the brain, making the temperature feel lower than the actual temperature for a longer period of time. [Endothermic cooling sensation (sugar alcohols)] The endothermic reaction that occurs when sugar alcohols such as xylitol and erythritol react with moisture (sweat) is used to lower the temperature of the entire fabric, giving it a cooling sensation.
