37.5 Thermoregulation Technology

The 37.5 Thermoregulation Technology helps to maintain your body at the ideal core temperature of 37.5 degrees Celsius and keep the micro-climate next to your skin at the ideal relative humidity of 37.5%. It's scientifically proven to increase stamina by reducing the amount of energy used to manage core temperature and improve efficiency so you use less energy to do the same amount of work.

It triggers off of humidity which is the gauge of whether you're hot or cold. When you're hot, the active volcanic sand particles embedded into the material use your body's energy to remove moisture and cool you down. When you're cold, the active particles retain body's energy to warm you up.

37.5 particles also trap odour molecules and then release them when they're washed and dried. Also, because those particles are permanently embedded in the fibre, they will last the lifetime of the garment.
