What is 37.5™ technology?
37.5® Technology helps keep your body at the ideal core temperature of 37.5° Celsius and helps keep the micro-climate next to your skin at the ideal relative humidity of 37.5%. When you’re hot, patented active 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.
