Set of 4 "Beastie" B4 quad fins. Full set also comes with Tectonics Maui quiver bag as pictured above.
Quite simply the best wave fins I have ever put in my board. The Wave Wizard was an amazing fin that I absolutely loved and the new Beastie line of fins goes one step beyond. The board feels faster in a straight line, more controllable, looser in the bottom turn and has more grip off the top. It is everything I am looking for in a wave fin.
