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 (245 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.

I bought 3 pairs of these socks (different colors) and I wear them a lot in the summer because they are good for my feet and I don’t get hot feet even in this hot summer! I highly recommend them!!!

You don't know how grateful I am for these Merino Wool socks. I bought them because they said they were breathable, and I found out when my son wore them to his soccer game. I cut the bottom of the team socks off so he could wear the merino ones. His team socks make him sweat a lot, causing blisters, but since he started wearing them, his feet have been drier, and it has helped keep his blisters from getting worse. I had tried everything from creams to other socks, even buying him more comfortable cleats, but my son's feet sweat a lot, and nothing has helped with his blisters. What I like most is that my son likes wearing them and hasn't complained that they bother him at all. So, I will buy more.
Thank you for taking the time to share your son's experience with our Microweight Cushion - Mini Crew Wool Socks! We are thrilled to hear that they have helped keep his feet dry and prevent blisters during his soccer games. Our Merino Wool socks are designed to be breathable and comfortable, so we are glad to hear that your son enjoys wearing them. We appreciate your support and look forward to providing more high-quality socks for your family in the future.

These are simply the best socks I’ve ever owned. The natural wicking technology of the Natural wool allows you to wear them all day without your feet smelling at the end of the day. I’m throwing away all my old socks and replacing them with these socks.

Great!
I like these socks a lot. Run 50 to 60 miles a week and wear these almost exclusively now. Provide enough cushion for both roads and trails. I will be buying more of these.

Ordered 2 pair for my son and I on a 20 mile hike. Very impressed with the fit and cushion of the sock. With the great fit of the sock, neither of us had any hot spots or blisters during the hike. Will definitely be buying more socks in the future.
Mike, we're so happy you're loving you socks, we love them too. Happy Hiking! -Felicia W.
