From concept to creation, Dylan wanted a fin that looked different, but worked as well (if not better) than any other fin on the market. What we got is the "Drunken Seagull" template and it's awesome! Dylan swears by it. Solid fiberglass to stiffen things up and to give it that glass on feel. Artwork by Mr. Graves himself.Enjoy!!
