No. 37.5 active particles are permanently embedded at the fiber level, work for the life of the product, and will not wash out during laundering.

In a study done by scientists at the University of Colorado Boulder, thermoregulation clothing with 37.5 Technology was scientifically proven to increase athletic performance by up to 26% by reducing the increase of core temperature during activity. Proven to decrease the rate of core temperature buildup and keep you cool more effectively than wicking. Scientifically proven to increase stamina by reducing the amount of energy used to manage core temperature. Proven to increase efficiency so you use less energy to do the same amount of work. This data can be found in the peer-reviewed journal article:¹
