Norrøna Trollveggen Heavy MerinoUll Socks in the colour Caviar Black/Iron Gate are thick and durable merino socks developed specifically for mountain climbing and demanding outdoor activities. The robust construction provides good comfort and warmth in cold conditions, while the natural properties of merino wool help regulate temperature as activity levels increase.

The socks are made from first-class merino wool that insulates effectively in the cold, while the material breathes and helps keep feet comfortable in warmer conditions. The natural properties of the wool make the socks well suited to long days outdoors, where warmth, comfort and durability are all important.

The socks have a mid-height length that pairs well with mountain and hiking boots. The merino wool comes from traceable, mulesing-free Edelweiss wool, supplied by Safil in Italy.
