Comfortable for everyday use as it is on the race day.

With Castelli's professional partnerships, top riders have provided hundreds of thousands of kilometers of real-world validation that the Aero Race 6 Jersey is their fastest short-sleeve jersey yet. This jersey takes a nod from speed suits and adds the best features into a summer-weight short-sleeve jersey.
 
Endurance cyclists might not think aero matters, but every watt saved is a watt you don’t have to push through the pedals. This jersey instantly ranks at the top for comfort, performance and fit.
