Castelli Sorpasso ROS Bib Tight When the mercury hits rock bottom, but the training needs to continue, Castelli’s Sorpasso ROS Bib Tight will ensure warmth and comfort throughout the ride. Designed for use on the coldest days, the tight combines Nano Flex 3G for insulation, water-resistance and fit with Nano Flex Xtra Dry fabric on front-facing areas and the backside for even better water and wind-resistance. An anatomical cut hugs the tight to the body in the riding position whilst still allowing total freedom of movement with the lightweight straps keeping it in place without compromising comfort or breathability up top. Zips at the ankles help when pulling on and removing the tight, with long reflective patches increasing visibility to traffic approaching from behind. At the core of the tight is a Progetto X2 Air seat pad made using seamless construction techniques so there is no discomfort or chafing.
