About 37.5 Technology:
Fabric made using 37.5® technology has thermoregulation properties that trigger off of humidity. It 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%. It has also been proven to increase comfort by removing moisture in the vapor stage, before liquid sweat forms, to delay the onset of sweat.
