The Smartwool Difference:

The Smartwool story started on a rugged Colorado ski slope with the belief that toes didn’t have to be cold.

One simple pair of Merino socks challenged the conventional wisdom and forever changed the way outdoor enthusiasts looked at their feet. It’s not just about the Merino, though. It’s what we do with it that makes Smartwool different. For over 20 years, we’ve been pushing the boundaries of Merino to create smarter, more capable products from head to toe.

Outfit Your Adventure:

Whether you’re running, hiking or riding, gear up to stay comfortable all day long. Merino wool is one of nature’s most advanced fibers, making it an ideal choice for high-performance clothing. The natural ability of wool clothing to breathe, wick moisture and resist odors make it a perfect choice for everything from pitching your tent after a long day on the PCT or shopping for fruit in a bustling Peruvian market. When you’re comfortable, everything else seems so much better.

    Get a larger size, they are smaller than size chart recommends. Also they are not long enough - I am 6 foot 3 inches and I have to pull them down and tuck into socks to get them to stay down CLOSE TO my ankles. They need another size range for TALL people.

    Everything about this is good, however I wore once no issue. Washed them, line-dried, and found a hole in the knee. No idea how that would have happened never even went to a knee to tie a shoe. Too expensive for a product fail like that, but it must have had a flaw that went noticed. I would order again, but make sure you inspect it better than I did.

    The best there is, comfortable for a range of temperatures.

    Great product. I have 4 pairs of these.

    Good stuff, but buy one size larger unless you want a stretchy compression fit.

    Made it through a cold upper-Midwest winter with no complaints.

    great product

    Too light
