The Castelli Rosso Corsa 9 is just like the Rosso Corsa 13 and 6, but with a medium-height 9cm cuff. Identical to the other versions, they are woven with Meryl Skinlife antibacterial fibers. Thanks to them you will be able to ride for a long time and still remain fresh. The sock is thus wicking, will feel dry pretty much in just about every circumstance save a rainstorm.
