37.5® TECHNOLOGY HELPS CONTROL YOUR CORE TEMP
NO MATTER THE ACTIVITY OR WEATHER

WARM UP &

COOL DOWN

37.5® Technology 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%. When you’re hot, patented active particles

embedded in the material remove sweat in the vapor stage before liquid sweat forms, cooling you down. When you’re cold, those same active particles trap your energy to help warm you up.

37.5® TECHNOLOGY IS MADE FROM NATURE

Our patented active particles are made from volcanic sand and activated carbon from coconut shells.

These microporous particles have the perfect combination of energy absorption and massive surface area to trap moisture and process it out of your microclimate.

Odor Trapping and Lifetime Lasting

37.5 active particles absorb and trap odor molecules so your clothes don’t smell, and then release them when they’re washed.

Speaking of washing, the active particles will work forever, no matter how many times you wash your clothes. Or how many times you don’t.
