The Capo Euro 200 are some of the finest socks you can purchase for the colder riding months of the year. The 200 number in the name comes from the 200 needle count construction the sock uses. Smaller and finer threads woven in a tighter knit results in a soft, comfy and durable product. The wool composition does a good job at wicking perspiration while maintaining thermal value. Wool, when done right is almost always a safe bet in a winter sock.
