THE SUMMIT AERO JERSEY has a slim, aerodynamic fit, ensuring less flap and wind drag through the shoulders and torso. It has been designed to hug the body and falls within the category of a race jersey. 

THE SUMMIT (TRADITIONAL) JERSEY has a more traditional fit and is a little roomier through the shoulders and torso. It's a good choice for those who prefer to not have a next-to-skin fit in the waist and belly.
