37.5® Technology helps keep your body at the ideal core temperature of 37.5° Celsius and helps keep the microclimate next to your skin at the ideal relative humidity of 37.5%. When you’re hot, patented active volcanic mineral particles embedded in the material remove sweat in the vapor stage before liquid sweat forms, cooling you down. When you’re cold, those same active particles trap your energy to help warm you up.
Cucumber + 37.5® Technology = the most comfortable clothes you own.
