Castelli Fatto 12 Sock

The mixture of Primaloft® and polypropylene yarns in the Castelli Fatto 12 Socks provide the rider with an especially light pair of socks that keep the feet warm and dry. When weight matters even in your socks, but the weather requires more protection, the Fatto 12 Socks meet your needs. For extra warmth, Terry-cloth has been woven into the socks and the reinforced toe and heel add extra support for the sock when worn inside a cycling shoe.
