Why We Like It

Cairn Subscribers were the first to get their hands on this upgraded version of the highly popular Ghost Runner. This ultra-light, no show sock now features 37.5 technology.


37.5 fiber contains active natural particles that increase the surface area of the fiber, allowing it to use body heat to evaporate moisture in vapor form (BEFORE it becomes sweat) which enhances body temperature regulation and humidity next to the skin. Sport Support keeps your sock in place with an ultimate fit while 37.5 maximizes evaporation, accelerates dry time, and enhances performance to keep you doing more, longer.
