Benefits of Merino Wool
Moisture Wicking
Merino wool is the best fiber to regulate moisture. It does this by absorbing sweat from your skin and releasing it into the air. Whether you're hiking, running, biking, on the job, or just relaxing at home, our wool helps keep you dry and comfortable all day long.
Soft & Comfortable
Merino wool fibers are much finer than traditional wool, creating a luxuriously soft feel that won’t itch or irritate your skin. Comfortable enough for everyday wear and gentle enough for sensitive skin, it’s a natural choice for underwear, base layers and next-to-skin comfort.
Highly Breathable
Merino wool’s unique structure allows air to circulate freely, helping to regulate your body temperature in both hot and cold weather conditions. Whether you're layering up for winter or staying cool in summer, Merino keeps you comfortable by letting your skin breathe.
Anti-Microbial
Merino wool naturally resists odor-causing bacteria, keeping you fresher for longer. No lingering smells, even after extended wear. Perfect for travel, outdoor adventures, and everyday life.
Insulates When Wet
Merino wool can hold up to 30% of its weight in moisture without feeling wet or clammy against the skin. Unlike cotton or synthetic fabrics, it keeps insulating when damp, making it a smart choice for unpredictable weather and high-output activity.
Fire Resistant
Merino wool is naturally fire-resistant and self-extinguishing. It will not melt or stick to your skin like synthetic fabrics. A trusted option for first responders, campfire safety, or any high-heat environment.
UV Protection
Our Merino wool clothing helps protect you from the sun’s harmful rays, with different levels of UPF based on fabric weight:
-
Microweight (145 GSM): UPF 20
-
Lightweight (170 GSM): UPF 25
-
Midweight (235 GSM): UPF 50+
-
Heavyweight (400 GSM): UPF 50+
These natural UV-blocking properties make Merino wool ideal for long days or the beach or above treeline.
Renewable and Sustainable
Merino wool is a natural, biodegradable fiber with a low environmental footprint. Grown by Australian Merino sheep and shorn seasonally, it is a renewable material that supports responsible farming practices.

A SOCK OVERHAUL
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.
YARN SELECTIONS

WOOL/NYLON YARNS
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.

HIGH WOOL CONTENT
We have packed in huge quantities of wool next to your skin, using the synthetics only as needed to improve fit and durability.

TECHNICAL FEATURES
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.
Fast shipping and the socks are awesome. They’re longer than I thought, and I’m a size 13 with pretty muscular calves. They go right up to the crease of my knee. They also stay up all day, which is most desirable. Very comfortable and very thin- thru dont make my feet sweat nor do thry smell at the end of the day.
I think I like this liner better than Darn Tough liner socks. It's a little early to tell. But I like the percent of merino wool on these. I would buy them again
I really like these socks. I’ve found it difficult to find knee high liner socks. The price is better than most and they feel and look if quality. I bought these for motorcycling. Will buy again.

I’ve put these sox thru the wringer over the last month and they’ve held up and really impressed. 2 days of lift access mountain biking in Vermont where they served as all weather (rain) gear and shin/calf protection from sharp flat pedal pins (small tear in sox, no tear in calf). 10 days of cross country mtn biking in NH and in Massachusetts including inclement weather, mud and many trips thru the laundry. Bonus: knee highs in solid light color help me find and remove ticks before they bite me. Add to that 2 days of hiking and a 6 day backcountry canoe camping tour including 12 miles of portage. These were a critical part my fast/light backcountry travel kit allowing me to travel, paddle and fish in sun and in heavy rain, including lining my boat thru the shallows and getting in and out of the water in combination with sport sandals to allow for relatively warm and comfortable amphibious and efficient cross country adventure travel in the Adirondacks. These sox have outstanding dry and wet weather performance. They stay warm when wet, can be worn over and over without accumulating odor, they fit my feet and legs better than other high end merino brands, cost less, show no signs of wear and are made locally from natural materials. 5 Star.
