Polygiene® is an active odor control technology for the treatment of high performance fibers, fabrics and other materials. Engineered to provide fresh-all-day confidence, Polygiene is perfect for active people who demand natural, long-lasting odor protection. Sweat is odorless but helps create the perfect environment for odor-causing bacteria to multiply. When sweat mixes with odor-causing bacteria on fabrics, odor results. Polygiene uses natural silver salt, a highly effective antimicrobial, to safely inhibit the growth of odor-causing bacteria but doesn't affect the friendly bacteria on your skin. And without odor-causing bacteria, you stay fresh. Key advantages Certified odor control Last the lifetime of the garment Safe next to your skin Environmentally friendly Works on all materials and colors Reduces static cling
