Castelli Tutto Nano Bibknicker XXX-Large BlackThe Castelli Tutto Nano is a Water-Repellent, Durable, Anatomically Cut bibknicker. The Nano features Castelli’s newest and most effective water-repellent technology, but it also functions just as well in dry conditions. The Nano Flex fabric used is not only warm but it’s incredibly soft and comfortable, and with the reduced seaming there’s fair less irritation while riding. For additional comfort, the KISS Air2 seat pad makes it easy to stay on your saddle for hours at a time.8055688933975
