The Trek's unique shape looks cool and also performs way better than the traditional round tube. Its extended rear corners act to stabilize the tube during fast whips and high launches off the wake. A smaller then usual center hole gives you a more comfortable seat by keeping you higher off the water. Also , the recess in the back makes a more comfortable cradle for your back when seated and for your stomach when lying in the tube. the outcome... better shape, better performance... great or ice!
