Cotton ball cap as shown in photo. They just get better looking with wear and age. The bill is normal size, not sure why photos make it look oversize. My hat blew off the boat in Cozumel couple weeks ago and the Capitan went back and we recovered it before it sunk. He told me what a great hat it was and how we couldn't leave it behind. Ok hang on a minute thats not entirely true. We turned around picked it up and he looked at me and said something in Spanish. This is the hat I wear most every day. looks good on me and it'll look good on you. Be a GENES diver, but a hat!! John
