A double layer of Primaloft Gold® results in an insulated sock specifically suited for cold Arctic temperatures with a risk of damp. Tough outer fabric, heavy duty fabric sole, and adjustable cord at the ankle makes for superb performance.

Primaloft Gold®

Primaloft Gold® is the ideal microfibre insulation. Ultrafine fibres produce an insulating core that is incredibly soft, lightweight and water resistant. In our experience it absorbs water much more slowly than other waddings, a marked advantage in wet-cold conditions.

The nearest of the synthetics to the feel of down, yet tougher than you would expect. Primaloft Gold® offers the best warmth/weight performance in the Primaloft range

Tough waterproof Tempest outer fabric (weight: 160 gsm)

A technically advanced waterproof breathable material. 100% Nylon. Good abrasion and tear resistance, yet offering high flexibility for such a tough material.
