TWO OF OUR BEST PRODUCTS COMBINED INTO ONEHeres a totally new way of thinking about riding in cold weather. With the product concept of the SanRemo SpeedSuit in mind, the Castelli engineers have unveiled a new way to dress warm and light for winter riding. By joining the jacket and the tight together we prevent cold air from entering, effectively keeping you warmer with lighter weight fabrics. There are no bib straps to restrict breathing, the seat pad is the same Progetto X2 Air as the one in your best shorts, and lightweight materials dont feel bulky or restrictive. You essentially have our favorite top, the Trasparente Light Jacket with our favorite tight, the Sorpasso. Joined San Remo style. It all adds up to winter comfort. Weve put all our best technologies into this exceptional Thermosuit. Aerodynamic cut, our best seat pad, and a mix of lightweight fabrics, including the WindstopperR X Lite fabric for total windproofness, and our warm Thermoflex Core Due fabric. By applying the technical advancement of hollow core fibers, weve made the tights not only lighter than your normal tights but also warmer and they keep you drier.
