37.5 by Cocona
37.5 by Cocona Technology has active particles that work with your body to keep you dry by actively moving moisture and accelerating evaporation. Comfort in clothing is greatly influenced by the temperature and humidity next to skin known as the microclimate. For the average person, the body strives to maintain an ideal core body temperature of 37.5° C. You are most comfortable when the microclimate next to your skin has a relative humidity close to 37.5%. When you are in this ideal 37.5 comfort zone, you are also in your ideal performance zone. 37.5 technology helps your body manage the moisture in your microclimate to keep you in this '37.5 zone' of comfort and performance.
