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

Woolen Yarn Wool Merino Sock Making New Hampshire

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.

NH USA made socks merino wool putting socks on to go for a run

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.

mountain heritage socks perfect to wear camping with your friends

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.

Not very warm…

These socks are nice but they are not very warm. I do a lot of ice fishing and my toes still get cold even with 2 pairs of socks. One regular pair and the outside pair are these expedition socks. I just received them a 2 weeks ago and with temps in the 20’s my toes still get cold when they’re advertised for temps below zero. The boots I’m wearing are thick Cabela’s pack boots also.

Jason,

Thank you for taking the time to leave a review for our Mountain Heritage Expedition Boot Socks. We are sorry to hear that you are experiencing cold toes while wearing our socks.

We understand how important it is to stay warm during activities like ice fishing. Our socks are designed to provide warmth in extreme temperatures, but it seems like they may not be meeting your expectations. We apologize for any inconvenience this may have caused.

Amazing products!! Seriously!

I have ordered 6 or 8 times from Minus33. They are truly a great company to do business with, and their products have all delighted me. First, I’m a very large guy and they have socks, wool tops, bottoms, and hats which actually fit me! You can easily TALK to them on the phone if you need to, and they go the extra mile if you have an issue or just need some help. Also, Merino wool is amazing by itself! It suppresses bacterial growth, so where I used to need to pack 7 or 8 pair of socks for a camping trip, now 2 pair are sufficient. Hopefully not ‘TMI’, but I take my socks off after 6 or 7 days of continuously wearing them, and I only smell the detergent that I used to wash them! Highly recommended!! John

Hi John!

Thank you so much for your kind words and for taking the time to leave a review. We are thrilled to hear that you have had such a positive experience with our products and our customer service. We take pride in offering high-quality products that fit all body types and we are always here to help in any way we can. Merino wool truly is amazing and we are glad it has made a difference for you on your camping trips. We appreciate your recommendation and look forward to serving you again in the future.

Not what I expected no great feet cushion

I’ve bought merino socks from other vendors that are very durable and these are not what I expected the ones I purchased before have thick cushioning and are actually less than half the cost that I paid for three pairs not impressed. Sorry being honest.
