Each piece in this collection was produced in Bangladesh with 100% polyester. Each hat comes equipped with a black crown, forest green top button and upper visor, cool gray under visor, black sweatband with the Hat Club tag affixed and a Northern Lights satin liner over the interior webbing. The front logo, side patch and flat-stitched batterman logo are sewn with a combination of icy blue, royal blue and pearlescent threading that changes color when in contact with sunlight.
