Castelli Sorpasso RoS Bibtight Cycling bottoms (3XL, blue) - Versatile cycling bib tights for chilly days - the Sorpasso RoS Bibtight from Castelli are the perfect choice when it's cold and dark outside. The insulating fabric made of Nano Flex 3G and Nano Flex Xtra Dry keeps your body pleasantly warm and dry. Due to its light compression effect, the fabric also improves stability and blood flow to the muscles while riding.In addition, the articulated knees and leg sections are especially adapted to the needs of cyclists. At the back of the Sorpasso RoS Bibtight, a water-repellent panel ensures that splashing water from the bike tyres doesn’t reach your body. Another great feature are the reflective elements which increase visibility in bad weather conditions.
