Why A Yak Wool Sweater Is Worth It

What goes into one, how long it lasts, and what each wear ends up costing.

Why Is Yak Wool So Expensive?

Because there is so little of it: only the soft layer under a yak’s coarse outer coat is used as khullu, and it is gathered as the animal sheds in spring. Our sweaters are then 3D-knit in one piece, so there are no seams to come apart.

Can You Wear A Yak Wool Sweater All Year?

Yes. Yak wool is a versatile fiber suitable for all-season wear. Its breathability allows it to keep you at the perfect temperature without trapping moisture. This means that even garments made with thin wool yarns are comfortable to wear in the summer.

Thanks to its moisture-wicking properties, wool doesn’t trap sweat, eliminating unpleasant odors. Furthermore, the inherent dryness of wool also discourages bacterial and mold growth. Consequently, yak wool sweaters can go longer without washing compared to other garments, without developing a lingering smell.

While you may not think of yak wool as a workout material, yak wool’s breathability and elastic quality make it suitable for a wide range of garments.

How Long Does A Yak Wool Sweater Last?

Many years with ordinary care, and that is where its value comes from.

Durability is another remarkable characteristic of yak wool. Its unique structure makes it even more robust than natural fibers like cotton. For centuries, wool has been transformed into garments that stand the test of time.

However, the extraordinary durability of yak wool takes this concept to new heights. When cared for properly, a yak wool sweater can last a lifetime, becoming a cherished heirloom passed down through generations.

The longevity of a yak wool sweater can be attributed to the unique properties of yak wool itself. The fibers possess exceptional tensile strength, allowing them to resist wear and tear even under demanding conditions.

Moreover, yak wool boasts natural elasticity, enabling it to recover from stretching or deformation without compromising its integrity. This characteristic ensures that the sweater retains its original shape and fit.

With proper care, wool clothing can stretch without losing its shape. That’s part of what makes the Oliver Charles All-Season Sweater great. I can roll up my sleeves, and they won’t significantly loosen when I bring them down.

From its robust structure to its versatility and other desirable properties, yak wool stands as a testament to nature’s remarkable craftsmanship and its ability to provide us with materials that are both functional and timeless.

Is Yak Wool Biodegradable?

Yak wool is biodegradable, making yak khullu an environmentally friendly choice for clothing. Synthetic clothing like polyester alternatively is made from plastic and is not biodegradable, so it can sit in landfills for centuries and leach microplastics into the environment.

Yak wool is a renewable resource that relies on the grassy plains of the Tibetan Plateau, sunlight, and, of course, the mighty yak.

Just like humans grow hair, yaks grow wool. On average, a yak can yield around 3 pounds of down each year. Yaks produce 5x as much soft wool as cashmere goats.

Why Has Yak Wool Been Worn For Centuries?

One of the most notable aspects of yak wool is its exceptional warmth and insulation capabilities. The harsh and extreme environments in which yaks thrive, such as the high-altitude regions of the Himalayas, have shaped their wool to possess unparalleled thermal properties.

The fibers are naturally fine, soft, and densely packed, allowing them to trap air efficiently and provide optimal insulation in cold climates. This inherent warmth makes yak wool an ideal choice for sweaters designed to keep you cozy and comfortable during chilly winters or outdoor adventures in frosty conditions.

Beyond its insulating prowess, yak wool offers an excellent balance of breathability and moisture-wicking properties. The unique structure of the fibers allows air to circulate and moisture to escape, ensuring that you stay dry and comfortable even during active pursuits or in fluctuating weather conditions. This breathability helps regulate body temperature and prevents the accumulation of sweat, making yak wool garments suitable for both mild and intense activities.

Moreover, yak wool can be sourced sustainably. Yaks are domesticated animals that have been a vital part of the local communities in the Himalayan region for centuries. The wool is typically obtained through a process called “combing,” where the loose fibers are collected from the yaks during their natural shedding season.

Yak wool’s exceptional feel, breathability, warmth, moisture-wicking, flame resistance, elasticity, and durability make it a standout choice for those seeking high-quality and functional wool garments.

Its unique attributes, coupled with its sustainable sourcing, contribute to the enduring appeal of yak wool as a remarkable fiber. The next time you wrap yourself in a yak wool garment, take a moment to appreciate the incredible qualities that make it a truly extraordinary choice.

Which Of Our Sweaters Should You Start With?

For one sweater that covers most of the year, start with the All-Season Sweaters. They are knit light enough for spring and fall and still warm on a cold day. For hard winters there are the Winter Sweaters, knit heavier from 100% yak wool.

Lasts For Years

A wool fiber bends more than 20,000 times before it breaks, which is why the knit holds its shape through years of wear.

Every Season

Breathes when it is warm and insulates when it is cold. It is comfortable in more months than a heavy knit.

Fewer Washes

Resists odor. Less time in the wash means it wears out more slowly.

Warm

40% warmer than sheep’s wool, so you need less of it to stay warm.

Soft

As fine as Grade A cashmere, so you can wear it on bare skin.

Repairable

Backed by a lifetime guarantee. A hole can be repaired.

Yak Wool Sweater Cost FAQ

What Makes Yak Wool Cost More?

Yes, up front: it costs more than sheep’s wool or any synthetic. Spread over the years it lasts, each wear works out cheaper than a sweater you replace every season.

Does A Yak Wool Sweater Need Dry Cleaning?

No. The All-Season line is machine washable and the Winter line is hand wash, so a dry cleaner never comes into it. Over the years you own one, that is a bill you never pay.

How Much Should You Spend On A Wool Sweater?

Work it out by the wear. A sweater you put on twice a week for ten years costs pennies each time you wear it, while one that loses its shape in a season has to be bought again.

Every good wardrobe starts with owning less and owning better.
