Castelli Fatto 12 Socks
This is a thin sock that performs like a thick winter sock. Made from a mixture of Primaloft and polypropylene yarns that are woven into a terry-cloth construction, Castelli's Fatto socks keep feet extra warm in cold, wintry weather. In fact, they protect feet from temperatures as low as -20°C/-68° F, but can still easily roll up for storage or travel.
