Imagine being able to ride in cold weather with clothing that emulated all the best features of your summer-weight kit: bibs that didn’t restrict breathing, a chamois as good as the one in your best shorts, and lightweight materials that didn't feel bulky or restrictive. The Castelli Sorpasso Bib Tights are part of Castelli’s Rosso Corsa line of products, and as a result, they get the Italian manufacturer’s very best treatment in materials, design, and fit.
