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 got two pairs of these for cycling. Other companies make something similar and then they quit making them. I thought I'd give Minus 33 a shot and i couldn't be happier.They are great in our South Texas heat and today I got caught in a gully washer and the socks were a little squishy but still comfortable. Just exactly the right amount of cushion for cycling.

After working through a very difficult delivery situation - USPS's fault, NOT Minus 33's fault - my socks arrived and I will say they are super comfortable! Soft, no itch with excellent cushioning. Kudos for Steven D. for the support through the delayed delivery!

I looked far and wide and even switched from past companies to discover Minus 33 wool ankle sox. Others have been reducing the amounts of wool smd other natural fibers. These are comfortable for all day wear in hot and cold weather. Great cushion and support where my feet need it.

these socks are very comfortable
The Microweight Cushion socks have been great through 3 wearings and washings. Very comfortable with the added padding and minimal shrinkage when dryer dried. Will be buying more.
Best socks I have ever owned.
I like these merino wool socks. It is hard to find socks with a high percentage of wool in their content, these do and are comfortable to wear all day.
So wicked soft and comfortable to wear in the dog days of August. That merino wool is cool! A great pair of socks!
Great softness and comfort.
These 59% merino socks are supportive but don't squeeze my toes together like some with a higher nylon content. They wash up well (air dry) and are pretty much the only socks I wear now.
Ruth,

Very comfortable.
Did not prevent blistering from walking five miles. OK for casual wear but somewhat thick.

I've tried on multiple brands of socks and these are by far my favorite. After putting these on, I now understand what actual cushion is supposed to feel like. I threw away all of my other socks and replaced them with these. I've had zero issues while running, weight training, and daily wear. I also get cold feet and these keep them warm throughout the day.

Was hoping it would have a little more cushion, but overall very good.
Both my husband and I have been wearing these socks for our long runs in mud, slush, and snow the past couple of weeks. They are comfortable and even in the mud and slush my feet have never felt wet or cold. I've worn them for over 100 miles so far with no signs of wear. I would recommend them for trail running.
Sarah,
We are pleased to hear that our Mountain Heritage Ankle Wool Socks - Full Cushion work well for long runs in the mud, slush, and snow.

The full cushion ankle socks were exactly what I was looking for. They don't sag during exercise and have held up well after several washes. And they provide the right amount of cushion for me.
Jamie,
Great to hear our full cushion ankle socks work well for you. They are great!
Thank you for taking the time to leave a review!

Hike thru an area Hawaii covered with black lava.
Moisture wicking and incredibly comfortable! I would go with the quarter or mid versus the low next time only because they seem to fall down some during hiking. Other than that, I love them!
Hi Amanda,
Thank you for the great review!
Jeannie T.
Minus 33 makes the most comfortable socks on Earth. They are even better now that they are made in the US.
Hi John.
Thank you for the great sock review! Glad you like are socks!
Jeannie. T
I am so in love with these socks! The fit, the feel and the durability gives me the warm and fuzzy's. As a mountain biker and hiker, I need good socks to get me where I need to go without discomfort or sweat. Can't wait to replace my subpar sock collection with these!
My wife and I have worn our full cushion ankle socks on two hiking trips on back to back weeks. We booted 18 miles and had over 3800ft of elevation gain. These socks will be on our feet and in our packs for all future hikes. Very comfortable and non slip, great wicking properties. We have worn lots of different socks by different manufacturers. We will be buying several more pair and these will be on our feet as we go over 6000ft. Thank you Minus 33!
