Polygiene® Permanent Odor Control – Polygiene® neutralizes odor by stopping the growth of odor-causing bacteria and fungi. Clothes stay fresh, odor free and can be worn several times without laundering. Also, Polygiene makes clothing last longer because bacteria and excessive washing don't break down fibers as quickly as they do on untreated material. Polygiene is safe next to skin and it's certified as bluesign® approved.
