The moment you enter the water with the StreamLine™ Training Board, you'll notice that this isn't just an ordinary kickboard. On the contrary, the StreamLine™ reduces and relieves unnecessary stress on your shoulders because it allows you to mimic the body's natural swimming position. Foam molded hand-grippers allow you to drive gracefully in a streamline motion while the tracking channels on both sides keep you in place and provide increased maneuverability for quick turns. So if you begin to drift, don't blame the board.
