Product details

Heavyweight Yak Wool Socks

With our heavyweight yak wool socks, you’ll never have cold feet again: Even in winter, the heavyweight construction keeps you reliably warm. They wick away moisture and excess heat, so your feet won’t overheat and will stay dry. The 100% yak wool we use isn’t just super warm—it’s also incredibly soft and reduces friction against the skin. It’s antibacterial and highly odor-resistant, so you can wear them odor-free for up to two weeks on your trekking trip. That makes our heavyweight socks the perfect companions for winter mountaineering, ice climbing, and ski touring—or simply as super-warm socks to wear in your winter boots.

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.

  • LIGHTWEIGHT

    Best weight-to-warmth ratio of any wool on the outdoor market.

  • ANTI-BACTERIAL AND STRONGLY ODOR-RESISTANT

    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
