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.
I purchased these socks at a discount through their pro program.
I was surprised to see these are 100% Merino wool, some other makers have a blend of materials for stretchiness and such but these are nice and stretchy without any of that. The microweight does seem to have slightly less stretch than the lightweight ones I also bought, just a smidge tighter around the calf, but not uncomfortably so; I bought the XL size because I have larger feet (US size 12.5-13), and these seem to fit nicely, definitely better than most big-store options that either only go to size 12 or are still just very tight at their "big and tall" sizes. Tiny bit more stretchiness would make these perfect for me but that's a personal preference.
They've become my everyday around-the-house socks now, the cushioning is great for cold floors without the rest of the sock being too warm; in fact they're even a bit cold right now in the Northeastern winter, so I'm excited about being able to wear these in other seasons as well!
I can buy a multi-pack of department store socks for less than the price of a single pair of these, but I can also wear holes in that whole pack of socks in the span of about a year; we'll see long-term how these hold up but it's immediately apparent that these are much more durable, so in the long run I think it's a much better value to invest in nicer socks like these ones rather than just going through packages of "disposable" socks.
They fit well and feel like they are going to last
