Castelli’s Nano Flex has been in the collection for seven years unchanged. It was seeming impossible to improve them, however the expert team as Castelli finally found a way.
By adding an insert to the back in a lighter Nano Light fabric the warmer conforms to the shape of your elbow, knee or leg far better than previously whilst still offering excellent water protection. More comfort due to enhanced flexibility as well as reduced bulk.
