The Swayback rack bag, new for 2014 is our newest rear rack bag. We heard customers want for more aerodynamic, a bag to work with lower seat heights, less Velcro, and more ways to lash gear. So we give you the Swayback. To keep the size we extended the length but lowered the front to fit under seats better. We still use our stiff foam on the sides to help it keep it shape no matter what you are doing.
