About the Castelli Passo Jersey The Passo Jersey is built on Castelli\\\'s famous Squadra all-around performer. It excels at everything from weekend racing, to training, to long days in the saddle. The main ProSecco Micromesh fabric ensures lightness and quick drying; the perforated side panels enhance breathability; and the construction of the sleeves, with no seams at the ends, provides unrivalled comfort. The YKK® zipper and the structure of the back pockets, which faithfully reproduce the characteristics of Castelli\\\'s WorldTour team\\\'s racing jerseys, complete the Passo. The result?
