Frigid winters and humid summers taught Darn Tough Vermont that all socks are not created equally. Living in the most unforgiving climate in the lower 48, their socks had to be tough and of course they certainly had to keep their feet dry and warm. Whether skiing, hiking, biking, climbing or running, our Darn Tough Vermont socks kept their feet oblivious to the elements. Their team spent over a year testing yarn combinations and designs, confident that during this process they could create something unique; a sock that they could guarantee for life. To date, DARN TOUGH VERMONT, is the culmination of those efforts. It's a brand uniquely created around a single, fine gauge needle, which means all Darn Tough Vermont socks, from their Mesh running sock, to their over-the-calf Full Cushion ski sock is crafted with the same high quality raw material and high density knitting techniques that make their product unique. Its custom counts of Merino wool and an exclusive blend of Coolmax® which makes their socks incredibly strong and comfortable. And it’s all about the knitting. Three generations of knitting know-how means, well, they know how. As they like to say, "We know socks, we wear 'em year 'round."™
