Thick weight, mid length waterproof sock perfect for a multitude of activities and conditions where added insulation is imperative.

  • Outer: 90% Nylon, 10% Elastane
  • Membrane: Hydrophilic membrane
  • Inner: 41% Merino Wool, 41% Acrylic, 14% Polyester, 2% Elastane, 2% Nylon
  • Finer than traditional wool with tiny overlapping scales that case each fibre, these scales are hydrophobic (water repellent). Inside it's a different story, the fibre core is hydrophilic (highly absorbant). Merino is therefore a wicking fibre and can absorb and release 10 times more moisture than synthetics. Each fibre can absorb up to one third of its own weight in moisture without feeling clammy or wet to the touch. In our socks and gloves, the moisture is then wicked through the membrane to keep you feeling warm and dry

Rated 5 out of 5 by from Perfect for outdoor activities I ordered 2 pairs right before my travel to Iceland. We had there all kinds of weatherconditions, but my feet have been alsways warm and dry. What else could you expect.

Rated 5 out of 5 by from Not just any socks... Sealskinz socks. A friend said he just wanted a pair of socks for his birthday. I thought "no way am I giving just socks as a birthday present". Then he told me the brand. I'd never heard of them. So I checked out the site - I immediately realised why he'd asked for "just socks" as a gift. So the socks arrived. I have to say, they have to be the best socks I have seen or felt. They scream quality. They look hard wearing and 'cool' at the same time. My friend loves them. He does a lot of walking so these will be put to good use.

Rated 5 out of 5 by from A must buy for heavy snow! I had done several photo trips in 6-10 inch snow and although my snow boots kept my feet warm, my socks would always end up wet because I didn't have a gaiter and my ankle felt freezing cold. With the Sealskinz socks I was amazed by how waterproof they were and how kept me toasty and dry every time.

Rated 5 out of 5 by from Fantastici. Ho provato ad usarli d'inverno con delle scarpe minimaliste (merrell glove 3) in montagna. Temperatura variava da 0 a +5 C, per circa 20 minuti ho camminato anche nella neve, il resto del percosso su sentieri asciutti. I piedi sono stati per tutto il periodo ad una temperatura confortevole. Al ritorno, dopo aver camminato per 8.00 ore i piedi erano asciutti. Non sono mai stato fermo per cui non so se stando fermo avrei sofferto il freddo. I piedi, nonostante le otto ore di camminata ininterrotta erano in ottime condizioni.

Rated 5 out of 5 by from Excellent outdoor socks Have worn several times and pleasantly surprised by these socks. 14 miles of wet and muddy walking conditions and feet stayed warm and dry.

Rated 5 out of 5 by from Warm and dry Feet feel like ice blocks 50% of the time, but these kept my feet warm and completely dry in a snow blizzard in Iceland... fab! Only note is that they're quite thick and I did struggle to fit my feet into my timberlands with these on, but still 100% recommend.

Rated 5 out of 5 by from Love these Use them for winter cycling, backcountry skiing and snow shoeing. I have cold feet and these keep them warm down to 20 F or so.
