Product details
Midweight Yak Wool Socks
Our mid-weight socks offer you the perfect combination of high-performance moisture management, excellent thermal insulation, and unparalleled comfort. In cold temperatures, they keep your feet comfortably warm while wicking away moisture and excess heat, ensuring your feet don’t overheat—even during physical exertion and in high temperatures—and stay dry. The 100% yak wool we use is extremely breathable and incredibly soft, reducing skin friction. It’s also antibacterial and highly odor-resistant, so you can wear them odor-free for up to two weeks on your trekking trip. This makes our mid-weight socks ideal for hiking, mountaineering, and trekking, and they're comfortable to wear year-round.
Important Note: Our socks use a special knitting technique and a unique yarn structure to provide greater durability than traditional yak wool socks. However, socks made of fine animal fibers such as yak wool are generally less durable than, for example, virgin wool socks. This is because fine-hair wools like yak, camel, cashmere, or alpaca have much finer fibers than virgin wool, which makes them more prone to breaking. Yak wool, however, resists friction well. Because we’ve further improved abrasion resistance with a special yarn structure, our yak wool socks offer by far the longest lifespan of any fine-hair sock.
However, they don’t match the lifespan of a wool-polyamide blend. With heavy use, you may need to replace the socks as early as one year. Only you can decide whether the significantly greater comfort, improved moisture management, and superior warmth are worth the annual investment.
The Benefits of Yak Wool at a Glance
Temperature-regulating
Keeps you warm in the cold and cool in the heat by supporting your body’s natural temperature regulation.
Breathable
Wicks moisture away from the body 66% more effectively than merino wool, ensuring a comfortable wearing experience. The most breathable wool on the planet.
Insulates against Cold & Heat
By insulating against the cold 40% better than merino wool, it keeps you comfortably warm even in the deepest sub-zero temperatures. In summer, it insulates against heat, so you’ll never get too hot on the mountain.
Prevents Heat Build-Up
Excess heat is effectively released to the outside, so you won’t overheat even during strenuous activities.
Keeps You Warm Even When Wet
Can absorb up to 35% of its own weight in moisture without losing its insulating power. Even after absorbing moisture, it offers more protection than other materials.
Protects against evaporative cooling
Minimizes evaporative cooling on the skin by immediately wicking moisture away, thus protecting against hypothermia in high mountains.
Highly Water-Repellent
Protects against light precipitation, wind, and fog.
Highly Wind-Resistant
Highly wind-resistant properties and a dense knit guarantee reliable protection against icy high-altitude winds in the high mountains.
Quick-Drying
Dries twice as fast as cotton and 17% faster than merino wool.
Lightweight
Best weight-to-warmth ratio of any wool on the outdoor market.
Anti-bacterial and strongly odor-resistant
Keeps you free of unpleasant odors for up to two weeks, even during strenuous activities.
Protects against UV rays
UPF 50+ for the highest UV protection in high-altitude mountain regions.
Antistatic & Flame-Retardant
Naturally antistatic, flame-retardant, and self-extinguishing.
REDUCED INFRARED SIGNATURE
Naturally possesses a reduced infrared signature in the near-infrared range (NIR-compliant)*
Soft & Itch-Free
Incredibly soft material that is itch-free and reduces friction against the skin.
Durable
Heavy, robust knit for a long lifespan. Up to twice as resistant to pilling as merino wool.
Sustainable
Sustainable sourcing of raw materials that preserves the high plateaus of Central Asia. Fair production by a local manufacturer in Mongolia.
SUITABLE FOR PEOPLE WITH ALLERGIES
Naturally free of lanolin, non-irritating, and breathable, making it particularly well-suited for people with allergies.
