Been looking for the end-all, be-all wool trail sock? We've been getting tons of requests for an ISW Crew, and it's finally here, in a 2pk.

The new ISW is a power-packed running sock built for the trail and beyond. Constructed with Isolwool®, the ISW utilizes merino wool and polypropylene to deliver superior moisture movement. A light cushion prevents blistering and enables prolonged performance in the harshest conditions. Wool naturally fights bacteria allowing the sock to remain clean and fresh. The ISW is designed to perform in hot or cold environments - and to excel on the trail.

They're knitted and currently available in limited quantities. Both Medium and Large now available with Orange highlights. Mediums also available in Limited Edition Pink highlights.

39% Merino Wool, 39% Polypropylene, 20% Nylon, 2% Spandex
