Stay cool, dry, and confident throughout the day with NanoDri Sweatproof Polo Shirts. Featuring Japanese nanotechnology, NanoDri polo shirts absorb your sweat on the inside but prevent sweat stains from showing on the outside. This technology functions all over the shirt, while allowing sweat vapor to escape and cooling you down by evaporative cooling. Made of ultra-soft and luxurious 100% micropolyester, NanoDri shirts wick sweat away from the body three times faster than cotton, and dry even faster. Additionally, they are stain resistant, repelling water-based liquids such as coffee or juice, and fat/protein suspensions such as milk. Additional features include a ribbed collar with interlining to help keep its shape, double-sided mesh to prevent clinging, and 100% waterproof membrane in the underarms. The wrinkle-resistant shirt is highly breathable and offers high stretch. The NanoDri polo shirt is available in White, Navy, and Burgundy.
