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.

These socks are a must! My feet run cold, so these are the only socks I wear in the winter. I've even skied with them, and they kept my feet warm. I do advise ordering a size up as they tend to shrink with multiple washings.
Great socks for hiking
I liked my Microweight socks so much I bought several pair for christmas presents.
A very comfortable sock for hiking
There is nothing that feels better than Minus33 wool socks on my feet. Absolute comfort and the quality is second to none.
Thank you so much for the glowing review! ✨ We’re thrilled to hear our socks have found a happy home on your feet. Comfort and quality are what we strive for, and it means the world to know you feel the difference. Thank you for being part of the Minus33 family- we’re so glad you’re here!
Most of my life I spent working outside through the winter in snow and below freezing temperatures. Many days ALL day. And I’ve been wearing Minus33 products for years, not just their socks. All of their products allowed me to stay outside, to stay warm, and to stay dry the whole time. I used to wear some other socks from a very popular ‘intelligent’ wool manufacturing company. There’s no comparison. These socks not only keep your feet warm and dry, but the particular blend of materials wear like no other. I no longer work outside that much, but I still have the same crew socks that have lasted for years, and I still wear them. No thin spots worn through the heels and no holes, they’re practically the same as when I got them and they go through the washer and dryer with no troubles. I would always recommend getting the full-cushion, but that’s me. I’m all about the comfort.

I like everything else about these socks except the narrow tight elastic top. I'm 5'2", 115 lbs, on my feet all day and looking for socks to wear all day every day. I love all the Minus33 products that I've tried yet, so I will keep searching the sock inventory to find something that will stay up without eliminating my circulation so much.
C.R,
Thank you for your feedback on our Full Cushion - Boot Wool Socks Mountain Heritage. We are glad to hear that you love our products and have found them to be a great fit for your lifestyle. We apologize for the tight top elastic and understand that it can be uncomfortable for all-day wear. We will definitely take your comments into consideration for future improvements. In the meantime, we suggest trying our other sock options to find a better fit for you. Thank you for your support.
Best regards,

These socks are very comfortable. Size Extra Large for 11.5 shoes. They are relatively thin compared to other full cushion socks, they almost feel like they could be used as liner socks. They do very well with my insulated boots, which don't have a lot of room for thick socks.
Cosmo,
Thank you for your review! We're glad to hear that our Full Cushion Boot Wool Socks are comfortable for you. Our socks are designed to provide maximum comfort while still being thin enough to fit comfortably in most shoes. We're happy to hear that they work well with your insulated boots!
Thank you for choosing our USA made Mountain Heritage collection!

Great fitting and warm socks!
I was introduced to Merino wool socks during a trip to Queensland in Jun'23 at an RM Williams store where I purchased a few pairs of their outstanding boots. The salesperson suggested some merino socks to wear with them. I was surprised by how comfortable, in QLD's warm climate these socks and later, in much cooler Sydney's climate, they were.
When I returned to the US, I searched for US made merino socks and after some research decided to buy some from Merino33. It was immediately clear how far up my calf the socks would go but a call to a very helpful person at Merino33 provided the information. For reference, RM's Chelsea boots are 6" high, and Merino33's Boot socks extend ~ 2" above them, so, very comfortable.
I was amazed at the quality, comfort, fit and style of the Boot socks I received. They're slim enough to be extremely comfortable in my RM's, but the well-padded support provided to my foot is similar to the socks given to you in a hospital setting to walk around in. The elastic support around the calf, mid-section of the sock and overall fit is outstanding.
I'll buy several more pairs in the near future as these are the only socks I now wear (apart from Minus33's crew socks). I wish there were more color choices available in this particular style, especially grey and argyle, but that won't preclude further orders. I highly recommend these to anyone for the fit, comfort and quality, and I'm equally pleased to support a US company manufacturing in the USA and using Aussie wool.
Bernie,
