The 2014 Aero Race Jersey is a significant leap forward in aerodynamics and weight, but Castelli kept the 2013 Free AR 4.0 Full Zip Short Sleeve Cycling Jersey for men in the line because it’s one of the most comfortable all-around jerseys they’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.
Saves approximately 12 watts at 40 km/h compared to a normal race-fit jersey
Velocity Dry fabric on front and shoulders for improved wicking and faster drying
Full-length Camlock zipper
Nervato fabric at arm holes for improved aerodynamics
