Castelli 2013 Men's Free AR 4.0 Short Sleeve Cycling Jersey A14019

TRICKLE DOWN GREATNESSThe 2014 Aero Race Jersey is a significant leap forward in aerodynamics and weight, but we've kept the 2013 model in the line because it's one of the most comfortable all around jerseys we've ever made. And it's still one of the most aero jerseys out there. Perfect fit and excellent moisture management with a nice fresh graphic. After introducing the Sanremo Speedsuit, we knew that a separate jersey and shorts would never be as aero for those days when absolute aerodynamics are a must. So we set out to engineer in better breathability and developed the new Velocity Dry fabric. We also changed to a full length zipper for ease of use and worked on the fit and stretch so that the jersey now fits more people, not just GC contenders at the grand tours.The marvel is that we made it better wicking, better fitting and easier to use, but we maintained the aerodynamics of the previous Aero Race Jersey. Wind tunnel testing shows this jersey providing a 10 to 12 watt advantage over our already aero Team jerseys at 40 kmh. That translates into about 35 40 seconds gained each hour.
