As many of you keep telling us, our Sleep Socks are one of our favorite products, ever!  

The sleep sock was designed to leave unrestricted circulation around the cuff - a top rising softly just above the ankle with no extra spandex ... just the natural stretch of the terry loop construction.  It adds the needed insulation to keep your blood supply in the feet comfy .. in bed, walking, or even with shoes or slippers. This version of the sleep sock is a yak/nylon yarn blend.

Slipping into a cozy pair of ultra-soft, wicking, comfortable, natural fiber sleep socks after a long day can be one of the most luxurious feelings. Not only do they help regulate body temperature by wicking away moisture, but socks made with natural fibers can also help prevent odors and fungal infections, making them a great choice for those with sensitive skin. Additionally, the softness and breathability of these socks can help promote a more restful night's sleep, as they won't irritate or constrict the feet.

They are warm, comfortable, and durable and we have it on good authority that they actually saved several marriages.


  • Stretch terry loop construction on inside, flat knit outside
  • Loose cuff bind off the top of the sock, less restriction on the ankle
  • Natural brown Yak fiber (no dyes)
  • Imported yarn
  • Knitted in USA

Sock Sizing

Socks should fit as well as any of your other garments. The heel should sit on your heel and not under it as in a sock too small, nor half way up your Achilles as in a sock that’s too large. Socks should be flush against your foot with no extra material sagging. The toe seam should lay flat across the top of the toes.

Sock Heel at Your Heel
The sock heel should sit on your heel, not under it or above it.

Flat Toe Seam
The toe seam should lie flat along the top of your toes, not above or below.

Taut Across the Foot
Socks should be taut across your foot with no sagging material. If you wear a wide shoe size (E+), consider sizing up.

How to Care for your favorite bison fiber gear

Material Composition

Here at The Buffalo Wool Co., our yarn bases for all our gear is (and will always be) natural fibers. This means that the internal structure of your socks (the parts that touch your skin) will be made from bison fiber, merino wool, mulberry silk, and other 100% natural fibers.

The overall composition (the parts that touch your skin plus everything else) will include other materials like nylon or polyester. This is done to make the sock more durable and ensure that your socks work (and play) as hard as you do.

Yarn Base Composition

70% yak down / 30% nylon (imported)

Overall Composition

55% yak down (imported) / 42% nylon / 2% Spandex / 1% polyester

Absolutely Love Them!

As someone who lives in Michigan we have cold winters and mid May it's still cold here this morning! I absolutely love these socks! I wear them to bed often during the winter! In the spring they are on my feet the minute I pop out of bed! I highly recommend them!


I love these socks so much, I bought some for my 81 year old father. They are warm and don’t constrict circulation. Once again, BWC gets it right!

Happy feet

I bought these socks for my girlfriend who has cold feet no matter what the temperature is. She says they are very soft and comfortable allowing her to get out of bed without the shock of bare feet on hardwood floors.

Finally, some sleep!

These socks are warm and comfy, and help me to fall asleep fast when I put them on after laying in bed for ages, unable to fall asleep due to cold feet. Get some, you won't be sorry!

Keep the feet warm

They fit good, they're soft, and they're tight enough to stay on, but not too tight.
