Castelli Primaloft 13 Socken

The Castelli Primaloft 13 are lovely socks for the winter season. The socks are made of a synthetic, insulating material. This fabric provides a lot of warmth and excellent perspiration transport. Also, 20 per cent of the socks is made of silk. This makes the socks feel wonderfully soft. At the toes and heel, they made a reinforcement for extra protection in sensitive areas. This makes the Castelli Primaloft ideally suited for the off-season.
