Our Womens ECOTEC PERFORMANCE knit polos in Print & Peached styles are made from moisture wicking and quick drying performance fabric and tailored for a feminine fit. Ecotec offers easy care as the micro-polyester yarn is infused with bamboo charcoal to create a natural sun block (UPF 50) and odor guard for the life of the garment. These shirts are not coated with the chemicals you typically see with performance shirts found in the market today.
