Yak Wool Long Johns

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.

• 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.
