Made with one of our all-time softest, most luxurious fabrics - both inside and out - this windshirt's shell is 100% polyester microfiber with a teflon coating, the number one finish against rain and stain. It is lined throughout with soft finish breathable nylon. "Railroad" desing on the knit trim puts you on a stylish track. Unique diamond stitching on the front forms handy side entry pockets making this windshirt stand alone.
