What is DR711 Anti-Microbial Protection?

Most "anti-microbial" fabrics only have a weak passive barrier against odor causing contaminants. Mach's DR711TM treatment actively absorbs and kills 99.9% of all microbes and bacteria that contacts it within eight hours. Mach's DR711TM treated fabric will stay odor-free, clean, and pleasant to wear through intense training and extreme use.
