The extra-warm Expedition Weight Merino Hiking Mid Socks from Patagonia feature a terry-loop construction throughout the interior and a toasty blend of Merino wool and nylon to keep feet warm in flash-freeze temperatures. The looped Lintoe® construction creates the smallest and flattest seam possible for maximum toe comfort inside mountaineering boots, and the tall rib-knit shaft holds the socks in place without binding or sloughing. Wickedly durable, they have excellent stretch and recovery that lasts the lifetime of the sock. Over-the-calf height protects your lower legs from big boots.


  • Fabric: 72% Merino wool/23% nylon/4% polyester/1% spandex
  • Chlorine-free Merino/nylon blend is itch-free and maintains durability for the lifetime of the socks
  • Excellent stretch and recovery
  • Mid-calf height

Excellent heavy duty socks!
January 03, 2012

These socks are fabulous. They are extremely soft and cushioned in all the right places, warm and the merino wool feels great against your skin. I tried them yesterday on a long hike in snow for the first time and they did an excellent job of wicking the moisture away. I had on ulitmax sock liners under the socks and double plastic climbing boots. The height of the socks works well - they come to just above the calf and were comfortably snug - no slippage. I wear a women's 5 or 5.5 street shoe and the small fit really well. Usually, I have a hard time finding socks that are small enough for my foot but these were great. Yes, they're a bit pricey but well worth the investment. If you're looking for a heavy duty, cold weather sock - these are the ones!

Pros: Great design, Performance, Ease of use
