37.5® Technology works with your body to provide dynamic thermoregulation and expand your comfort range, regardless of the activity.

The Comfort Zone

37.5 Technology is powered by the human body and triggered by humidity. Where wicking only moves moisture, 37.5 Technology actually removes it. This helps your body adapt to the environment and create a microclimate of personalized comfort. Our temperature regulating material technology expands your comfort range, regardless of the activity.

Head to Toe

37.5 Technology particles actively attract moisture and then use your body’s own infrared energy to speed the release of this moisture to the outside environment, leaving you drier and more comfortable—head to toe.
