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. The Sorpasso Bib Tights begin with Castelli's top-of-the-line Progetto X2 pad, the same pad found in their best shorts. The top layer that contacts your skin is a made from a seamless, four-way stretch microdenier fabric designed to move in harmony with your body and eliminate the chafing that can come with materials with too little stretch. It receives an antibacterial treatment and is bonded to a variable thickness pad made from multiple density foams; the result is a smoothly contoured pad that places the firmest foam where support is most needed. Perforated inserts help to relieve pressure on the sit bones and perineum -- just where riders experience the greatest pressure. The front of the tights are cut from Thermoflex Core Due to keep the wind out. This two-layer material traps air in a hollow-core layer of polyester while moisture is transported to the outer nylon/Lycra layer where it can evaporate. A simpler fabric, Thermoflex, is used for the portions of the tights not exposed to the wind for greater breathability. Giro++ grippers keep both the bib straps and ankles in place. It's rare to find bibtights that are this light and this warm. Like the bibs in the Rosso Corsa line, the waist of the Sorpasso Bib Tights is cut very low to eliminate restrictions on breathing caused by pressure on the belly. The Castelli Sorpasso Bib Tights are Black/white and are available in six sizes from Small through XXX-Large. Read More »
