When Castelli puts a bib knicker into their first-rate Rosso Corsa line, you can count on all of their best technologies to be thrown in. The Sorpasso bib knicker is built with the Progetto X2 Air chamois and innovative Thermoflex Core Due fabric to keep you feeling dry, even in wet conditions. Using hollow-core fibers that repel moisture, these knickers are not only lighter and warmer than normal, but they keep you drier. Lightweight, laser-cut bib straps lay flat beneath your jersey, while a mesh bib panel allows moisture to evaporate. Silicone gripper below the knee keeps the knickers in position. Now you're ready to put in those long base rides all winter long. Recommended for temperatures between 57°F and 68°F.
