Castelli 2008 Rosso Corsa Superleggera Cycling Jersey Red A7002 023

Simply put, this is the lightest cycling jerseyweve ever created. This feat of science wasachieved by using SG0.6, a revolutionary fabricthat is polypropylene with a hollowed out core. The result is a jersey that weighs only 70 grams!Thats less than half the weight of a typical jersey when dry. And less than a third when wet only 140 grams compared to 400. In championterms, this amounts to a full minute in a Tour deFrance mountain stage.
