This top contains 37.5® technology which works with your body to determine if you need warming or cooling. 37.5® particles absorb the infrared energy your body emits and if moisture/sweat is present it speeds the evaporation to cool you. If no moisture/sweat is present the infrared energy is retained to keep you warm.
