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.

The perfect winter sock

They are nice and heavy for the winter months. The crew height is perfect. Most other wool socks are way to tall. They work well with shoes or hiking boots.

Much Better

The first pair I got were too small and after washing they were very tight. and that was the largest pair they had in that style. Contacted them and offered to send a different style that were a little bit larger. They were much better. would still prefer a pair with no elastic in the foot part of the sock. But I have not been able to locate of those. I have had 1 pair with no elastic for over 15 years and they still are usable but starting to wear out. I only wear them at night to keep my feet warm. Ron

Hello Ron,

Thank you for taking the time to share your feedback with us. We are sorry to hear that the first pair of socks were too small and tight after washing. We are glad to know that the replacement pair we sent were a better fit for you. We hope you continue to enjoy your Expedition Crew Socks and we appreciate your loyalty over the years.
