CLEANSPORT NXT is the name given to naturally-occurring beneficial microbial enzymes. Using a special technology these live enzymes are bonded to our fabrics where they remain dormant until exposed to moisture. The microbes are activated by moisture from perspiration. Perspiration contains odor-causing bacteria. CLEANSPORT NXT organisms thrive on this odor-causing bacteria thereby eliminating odor biologically. As the moisture dries, the organisms return to a dormant state until moisture is present again, when they then return to an active state. This cycle is repeated whenever moisture is present. The benefits are natural, non-toxic odor-elimination with no harmful bi-products to you or the environment.
