The Sanremo Thermosuit combines two of Castelli's best products for warmth and a steamlined profile. 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 Castelli prevents 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 don't feel bulky or restrictive. You essentially have Castelli's favorite top, the Trasparente Light Jacket with their favorite tight, the Sorpasso. All joined San Remo style. It all adds up to winter comfort. Castelli has put all their best technologies into this exceptional Thermosuit. Aerodynamic cut, Castelli's best seat pad, and a mix of lightweight fabrics, including the Windstopper® X-Lite fabric for total windproofness and warm Thermoflex Core Due fabric. By applying the technical advancement of hollow-core fibers, Castelli has made the tights not only lighter than your normal tights but also warmer - and they keep you drier.
