All the best technologies have been put into the Castelli Sorprasso Women’s Tights. Progetto X2 Air women’s-specific seat pad, and a mix of lightweight fabrics, including warm Thermoflex Core Due. By applying the technical advancement of hollow-core fibres, we’ve made these tights not only lighter than your normal tights but also warmer, and they keep you drier. Ankle zips are YKK Camlock, and covered with reflective tape for night visibility. Now you’re ready to put in those long base rides all winter long.
