Carhartt WIP Marlin Cap - TreehouseErnest Hemingway wrote a few yarns about big game fishing and reeling in huge Marlin. The Marlin Cap is an unstructured six panel design, with a rigid, curved peak. An adjustable self fabric backstrap with metal hardware and strap tuck eyelet. A fine print of this sizeable sea dweller to the crown, which is often fished off the Florida Keys, Bahamas and Cuba. Embroidered Carhartt script rounds it out.
