Castelli’s Nano Flex water-repellent fabric is one of those fabrics that seems miraculous. On a dry day its as warm and breathable as the normal Thermoflex fabric, but when it rains the water just runs off, thanks to the five phase nanotechology treatment. While its not 100% waterproof, its the best soloution Castelli has ever tried for staying comfortable in any conditions. Ideal for spring showers the Nano Flex bib knicker features a kiss 3 seatpad for all day comfort.
