The Castelli Sorpasso RoS is the ideal long bib tight for avid male cyclists who like to continue their training rides in winter. Ultimate cold protection The Nano Flex 3G fabric not only makes the Sorpasso RoS comfortably warm, it also repels water very well. A short rain shower will not be a problem, but do keep in mind that heavy rain will eventually penetrate the material. To give you additional protection against wind, rain and cold, the front, back and thigh sections are made of Nano Flex Xtra Dry material. The Castelli Sorpasso RoS fabric is highly stretchy for a comfortable fit. Progetto X2 Air seat pad Castelli's Progetto X2 Air seat pad is ideal for cyclists who like to make long rides. This chamois has been designed to protect your skin well, and has the right thicknesses to protect you no matter how many hours you spend in the saddle. The top layer is made of 4-way-stretch microfibre and has no seams to create minimal friction during cycling. The foam in the seat pad has been perforated by Castelli to make it highly breathable. The chamois has two different sections to give you the best support where you need it most. Anatomic fit with light compression Because the Sorpasso RoS is pre-shaped into the cycling position, it has as few creases as possible during cycling. This can be seen in the curves at the knees and hips. The used fabric stretches well and has a pleasant tight fit around the legs. As such, it provides light compression which supports your muscles well during cycling. The bib straps keep the tight well in place and lie flat on the body so they don't cut into the skin. The reflective elements complete the Castelli Sorpasso RoS long cycling tight and ensure that you are highly visible during the cold, dark winter months!
