Castelli Sorpasso Bib Tights surpass your typical winter bib tights in lightness and warmth. A combination of two insulated materials, one that is subtly water repellent and another made from of hollow-core fibers that reject moisture, works to keep your skin warm and dry. Giro++ bib straps hug your body in seamless comfort, and the same seamless material is used in the leg grippers to form a snug seal around your shoe covers. The varied-thickness Progetto X² chamois provides the highest level of comfort that Castelli has to offer.
