Wadding with Valtherm Active Powered by 37.5® Technology adapts to your needs to help control your temperature, expanding your comfort range even when your environment or activity level changes.
Now the same jacket can keep you comfortable in a tense meeting, a long flight, a frigid board room, a twenty-block walk, or a run through the train station.
HOW DOES IT WORK?
It works with your body to determine if you need warming or cooling based on the amount of humidity next to your skin, which is the body’s way of expressing whether it’s hot or cold.
The active particles capture the infrared (IR) energy your body emits and if moisture is present it speeds the evaporation to cool you.
If no moisture is present, the IR energy is returned to keep you warm.
