Each piece in this collection was produced in Bangladesh with 100% polyester and comes equipped with a Northern Lights graphic satin liner on the front-interior panels. Each hat features a light purple crown, indigo upper visor and top button, classic gray under visor and black sweatband with the Hat Club logo affixed. The front logos, side patches and flat-stitched batterman logos are sewn with a combination of dark purple, icy blue and heat-activated threading that changes from pearlescent to electric purple in the sunlight.
