Castelli 2012 Men's Aero Race 3.1 Short Sleeve Cycling Jersey A12010

FASTER THAN EVER. This is the jersey that started the Aero revolution back in 2007 and has been imitated by nearly every manufacturer and team. It has been in continuous evolution ever since and weve now exceeded 70 prototype iterations in our quest for speed. For 2012 weve improved the airflow in the area behind the shoulders and along the side panels using some innovative basic aerodynamic research and consulting with leading experts. And of course continuous testing on the road and with the Garmin Cervlo team. THE MOST AERODYNAMIC RACING JERSEY WEVE EVER MADE. SAVES APPROXIMATELY 12 WATTS AT 40KMH COMPARED TO A NORMAL RACE FIT JERSEY. VELOCITY FABRIC ON FRONT AND SHOULDERS WITH. PROSECCO TREATMENT TO KEEP YOU DRY. OPEN MESH BACK AND SIDE PANELS FOR BREATHABILITY.
