VERSATILE BY EVOLUTION

It all begins in the Tibetan plateau with these furry fellas. As the highest-dwelling mammals in the world, yak live through a considerable range of temperatures.

Their ability to both survive in -40° F winters and thrive in 90° F summers is highly dependent on the evolutionary abilities of their luxurious khullu fiber.

KHULLU ("COO-LOO")

Every spring, yaks naturally shed their fiber. All the herders have to do to collect it is simply brush the animals. Although, most of it is hand collected by herders as it sheds. Yaks are healthier when their wool is combed out. The process of gathering khullu helps yak keep cool leading into the 90°F summers.

Yaks are kept by nomadic herders so they aren't locked away in cages or confined to small pins. They get all the open space they could ever want to run and play.

GOODBYE CASHMERE

Khullu is some of the highest performing wool… we go as far as saying it’s the world's best wool. This is largely due to the evolution of the fibers that help yak survive dark cold winters and sunny hot summers. The more intense the environment of the wooly mammal, the more versatile and high performing the fibers will be.

Yak live at elevations of up to 15-20,000 ft while cashmere goats live at elevations of up to 10-15,000 ft. The environments yak roam are colder and more rugged than their goat peer, so it’s likely that the fiber is warmer.

What we do know from research is that yak wool is 30% warmer than sheep wool and nearly 2x more breathable than cashmere.

FOR EVERY 5 CASHMERE GOATS, THERE IS 1 YAK

Cashmere goats have caused 70% of Mongolia's grasslands to turn to desertsYak are low carbon emission animals that do not significantly contribute to desertification.

Khullu is an ideal cashmere alternative that has a similar luxurious, soft feel. However, unlike cashmere, sweaters made from khullu are easy to care for.
