The Velocissima DT 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 the specifically designed suspenders that allow for a physiological break without having to take off your jacket and lower the suspenders. It has a reflective band around the bottom of the leg and a YKK® Camlock® ankle zipper to ease the heel passage.
