37.5 technology helps keep your body temperature at the ideal core temperature of 37.5 Celsius and helps keep the microclimate next to your skin at the 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, the same active particles trap your energy to help you warm up.

37.5 technology is built up from coconut shell and volcanic sand embedded at the fiber level meaning industry leading wicking properties keeping you comfortable and dry.

These properties will never wash out, unlike many other wicking treatments.

Volcanic sand and activated carbon from coconut fiber creates 800% more surface area keeping you dryer, more comfortable and performing at your peak level.
