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.

Socks are great, very comfortable, but I wish Minus 33 had a line of Merino socks at this and all lengths that had much looser tops…

I like these for when I wear my hiking boots. Cover to top of boot. Not bulky to wear. My feet don’t sweat with these, so good for warm weather. No sliding down noted; don’t cause constriction to blood flow.
- They fit perfectly, wash very well, keep their shape, and are super comfortable.
- I'm not sure I've ever put on a better fitting sock.

I bought socks for everyone at Christmas but this was the first time they got Minus33. It was a huge hit and my son who wears size 13 tells me that besides being warm they fit him so much better than the Bombas he got last year
Love these socks, comfortable and perfect fit.
I am going to buy more
Very comfortable.
Very comfortable, will definitely get more!

I live in Florida and do a lot of cycling. I needed some super thin, low socks since my old cotton cycling socks wore out. I saw these and thought I would give them a try. They fit perfectly, wash very well, keep their shape, and are super comfortable. They definitely absorb sweat but don't feel wet. I never thought of wearing wool in a hot climate, but these thin socks are fantastic! And I have some sneakers that are a bit snug so these are perfect for long walks. Going to Norway next month on a northern lights cruise and will definitely wear these for the 24 hour travel day, and as a sock liner under my heavier wool socks. The buy three get one free deal is fantastic! I've used it twice now. Your products are top quality!

I’m not sure I’ve ever put on a better fitting sock.
My husband loves these sock liners! He said his feet don't sweat and they are so comfortable that he doesn't want to take them off! He plans on throwing away all of his other socks and buying more of these.
Well-fitting and stay up. I wear the ankle socks all summer with capri pants and these are perfect. It is hard to find the beige/khaki color, so I bought another pair just to have two!
