Climbing the most technically challenging terrain in the world is just another day at the office for Conrad and having the best cold weather gear is critical to his success.

In searching for the best cold weather socks for climbing, Conrad found a perfect partner in our master sock developers. His attention to detail, years of experience and on-mountain field-testing helped us create our most technical mountaineering socks ever.
