Swiftwick Pursuit Ultra Light is designed as an all season sock suitable for any adventure.  The addition of Swiftwick’s signature Olefin fibre to the proven outdoor performance of Merino Wool makes it the driest sock in its class. Lightweight Olefin wicks moisture and dries quickly, while the unique structure of Merino Wool absorbs moisture without feeling soggy or losing the ability to regulate temperature.  It also includes a reinforced heel and toe for greater durability in abrasion prone areas.  The ideal sock if wool is your preferred fibre to wear or if you want to take the edge off a cool autumn or spring morning.
