Castelli Sorpasso ROS Womens Bib Tight Castelli's Sorpasso ROS Womens Bib Tight will keep you warm through the coldest winter conditions. It incorporates two main fabrics; Nano Flex 3G and Nano Flex Xtra Dry, the latter in panels on the upper front and thighs where the elements hit hardest. The super-soft materials are incredibly warm, repel water, and provide compressive support to the muscles. Cut for the riding position, there's no restriction to movement while you pedal.  A Progetto XS seamless Donna seat pad takes care of you in areas of contact with the saddle, absorbing shock and providing enough cushioning for the longest rides. The tight is supported by elastic bib straps that sit smoothly against the body, and YKK® Camlock® zippers at the ankle make the tight easy to pull on and remove. Finished with reflective inserts, approaching traffic will be better alerted to your presence on the roads.
