Merino Sock

Extensive clinical study and mounting evidence in various fields of research has led scientists around the industry to conclude that Merino wool is rad. It's naturally odor-resistant, extremely breathable, and the insulating archetype that all these hollow-core synthetic yarns are mimicking. When fashioned into a tube, ribbed around the ankle, and reinforced to support the midfoot arch, merino provides a platform for a fantastic cool-to-cold weather cycling sock, and that's exactly what the Castelli Merino Socks are.
