The Heavyweight Mountaineering sock was built to be our warmest sock for winter mountaineering. On the coldest days, when you can't even imagine going outside, this sock will become your best friend. A perfect fit for any cold-weather exploration, frigid adventure, or just shoveling the driveway snow, it delivers time and again. Don't get caught without them!

We got our sock machines set up in May of 2019, and hit the ground running. We knew our customers wanted a sock for every occasion, with heights and cushion levels for all activities. By combining our historic textile knowledge, and using what we learned after redesigning our classic sock styles, we were able to envision a brand new sock collection that could truly meet your needs.
We dialed in our yarn selection, using a combination of merino/nylon as the main body of the socks. These yarns deliver a high merino wool content, with the extra durability of nylon.
We have packed in huge quantities of wool next to your skin, using the synthetics only as needed to improve fit and durability.
Stretch nylon yarns are light enough to keep the merino content high while giving shape and fit to the sock. Lightweight plating also adds durability to high wear zones on the heel and toe.
Got two pair of these just before winter hit in South Dakota. -40 degrees and the wind would cut right through. If you want a pair of socks that keep you warm and dry, these are the ones for you.
John,
Thank you for leaving a review for our Mountain Heritage Expedition Mountaineer Over the Calf Socks. We're thrilled to hear that our socks were able to keep you warm and dry during those harsh -40 degree South Dakota winters. Our goal is to provide our customers with high-quality products, and we're glad to have met that with you.
Stay warm,

It has not been cold enough to wear these socks yet. I did try them on and compared to the light weight and mid-weight Merino wool socks sold here they do not come as high up over the calf.
Dear valued customer,
Thank you for taking the time to leave a review for our Expedition - Mountaineer Over the Calf Socks Mountain Heritage. We appreciate your feedback and we understand that it has not been cold enough for you to fully test out the socks yet.
We would like to assure you that our socks are designed to provide warmth and comfort for cold weather conditions. However, we understand your concern about the length of the socks compared to our other Merino wool socks. We will take note of your feedback and use it to improve our products in the future.
We hope you will give our socks a chance when the weather gets colder and we are confident that you will be satisfied with the quality and performance of our Expedition socks.
Thank you for choosing our brand and we look forward to serving you again.

These socks make it seem as though I was wearing slippers in the woods. All day comfort both cushion and warmth!
