The Velocissima Thermal Tights are the right tights for cool or moderately cold days. They feature the KISS Air2 Women's chamois, ideal for medium-distance rides or if you don't need the padding of the Progetto X2 chamois. These tights are warm but are more suitable for dry days as they don't have the water-repellency of the Nano Flex tights. It is more than likely that these are the conditions you are riding in and that the Velocissima is right for you. The fabric is our super-soft, brushed Thermoflex. It has special details like an extra-soft waistband and a reflective band around the bottom of the leg with a YKK® Camlock® ankle zip for easy heel passage.
