Castelli Gregge 12 Sock
100% merino wool. The beauty of merino wool is its versatility. These socks are recommended for cold and windy conditions, but they can really be used in any weather. The Gregge 12 is a very soft sock that will keep your feet warm and comfortable, all while wicking away moisture. Excellent breathability means your feet won't suffocate and leave your toes tingling in the process.
