The embroidered crown is derived from Guy Harvey's dramatic art of a jumping blue marlin with his famous signature above and behind this magnificent fish. Crafted from brushed 100% cotton twill fabric, the Guy Harvey Blue Appliqué Hat features a Velcro-adjustable back strap to allow for a customized fit. As is the case with all Guy Harvey sportswear, your purchase of this Guy Harvey hat will contribute to the over $200,000 that AFTCO Bluewater contributes each year to the Guy Harvey Ocean Foundation for its marine conservation efforts. Imported. One size fits most.
