Castelli

When the forecast calls for 100% cold with 0% chance of riding, Castelli's Sorpasso Bibtights save the day. For warmth in the worst weather, Castelli fashioned the Sorpassos from their stretch Thermoflex and Core Due fabric that features a wicking outer layer and a soft, fleecy inner for extraordinary warmth. The chamois is Castelli's top-of-the-line Progetto X2. It's seamless, antimicrobial, has 4-way stretch and features multi-density foam of varying thickness for the pinnacle of comfort. And with reflective rear zips, Castelli's Giro++ bib straps and ankle grippers that seal around your shoe covers, these tights keep you riding no matter what the weatherman says.
