Tibetan yak wool
Yak wool is hypoallergenic, naturally antimicrobial, and insulates without overheating. We knit it into an everyday crew that fits in a dress shoe, a full-cushion boot sock for the coldest days, and a beanie that is thin for how warm it is.

Three ways to wear yak
Everyday crew · 2 pack

Boot sock · Full cushion
Full cushion through the footbed for all-day wear.
Beanie · 50% yak, 50% merino
Deep-winter warmth without the bulk.
Why yak
Warmth per ounce
Yak wool runs 30–40% warmer than merino at the same weight, so we can use less of it to get the same warmth. The sock stays slim, the beanie stays thin, and neither one overheats.
Skin
Yak fiber is gentle on sensitive skin and naturally antimicrobial, which is why it fights odor on its own. Moisture-wicking keeps feet dry.
The beanie
Most beanies make you choose: warm but bulky, or comfortable but not quite deep-winter warm. Half yak, half merino means you do not have to.

The Yak Wool crew socks are some of the softest, most comfortable socks I have ever worn. They are well made and fit well. My wife and I both love them.
Wonderful, cozy socks. They are breathable and comfy for anything ranging from a cold Wisconsin winter to a more mild south Texas winter.
These are genuinely the best, softest socks ever. Keeps my feet warm but never sweaty. I have recommended them to anyone who will listen.
Sock are soft and really warm. Wore them when it was 6°F out, and had no problems.
Just as warm and functional, just softer than the bison socks!
I wore this hat when I was outside shoveling snow, while it was still snowing. It kept me perfectly warm, even when it was covered in snow and wet. I didn’t even notice it was wet until I came inside and took it off.
No. Yak wool is hypoallergenic and gentle on sensitive skin.
Yes. Yak wool is naturally antimicrobial, which helps fight odor over time.
They are a sleeker, low-bulk sock. For full cushion, choose the Yak Wool Ultimate Full Cushion Boot Sock.
S/M fits women’s 6–9 and men’s 5–8. M/L fits women’s 10–12 and men’s 9–13. The beanie is one size fits most.
Yak wool runs 30–40% warmer than merino at the same weight, so a thinner knit gives the same heat.
