When Castelli first introduced the aero jersey to the pro peloton in 2007 it was seen as radical. By 2009 all the pro teams were jumping on the bandwagon, and in the following years the aero revolution steadily spread to more and more cyclists. This is a women's-fit version of the full World Tour level aero race jersey, the fastest jersey they've ever tested. But they haven't limited it to racing: it has a full-length front zipper for easy on/off, a zippered pocket for valuables, three full-size rear pockets for carrying cargo on your long rides, and excellent moisture management fabrics throughout. When Castelli started engineering aero jerseys nearly a decade ago they didn't imagine they would become the new normal, but you'll find that every ride is faster and more fun in this new not-only-for-racing jersey.
