Whether you’re camping, birdwatching or just enjoying a day out in the country, these Mens Original Outdoors Merino Wool Blend Socks in Black will keep you warm and comfortable no matter how long you spend outdoors. They’re made with Merino wool, a natural fibre with amazing thermal and moisture management properties that feels far finer and softer against the skin than regular wool.

Heat Holders Outdoors thermal socks are an evolution of our classic and warmest Original thermal socks, designed to bring you unparalleled warmth, comfort and protection in all your outdoor activities or pursuits. These Original Outdoor Merino Wool socks boast an even higher 2.9 TOG rating, making them over twice as warm as an ordinary thermal sock and more than eight times warmer than a basic cotton sock!

To meet the demands of the outdoors, we’ve boosted protection and durability in the heel and toe, which usually see the most impact and wear. We also use a special fibre blend and knitting structure for these elements, making them more resistant to abrasion (rubbing). The result is a durable yet wonderfully wearable outdoor sock that will keep you warm and comfortable whatever your outdoor pursuit.
