100% pigment-dyed, water-washed cotton twill fabric has been crafted with the modern quality of a tried-and-true process that keeps the color intact and the fabric shrink reduced. Larger pigment particles are bound onto the fabric, and no chemical reaction takes place. This instantly adds the dulled coloration and a softer hand than dyed materials. Embroidered eyelets improve air circulation, and the antique brass snap with tuck-in closure completes the classic look and makes this hat adjustable to almost any size.
