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.

Small 3 – 6.5

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

Awesome Sleep Sock

Best sock for those who need to keep their toes warm when they sleep! No binding or pressure around your foot or lower leg. You don’t know that the socks are there except your feet feel great! You can’t go wrong in getting these socks for cool or cold feet. They will be an issue in the past once you get your pair on.

Love em! Make em longer!!!

I love the sleep socks!! Having cold feet, I wear them to sleep in all winter and into spring and summer when the temps dip low.
I also wear them as socks on cool mornings.
I bought additional pairs when they were on have on hand - and for camping adventures
I wish you would have them manufactured in a longer length, as I would wear as daily wear socks. The current length is too short - and there is a gap between the cocks and pants (oh so cold!).

Denise S. (Miami, US)
These are flipping awesome !!!

First off let me say that I got these for my hubby because he is a diabetic and gets COLD feet! He travels a great deal and now refuses to go without these. I have gotten several other styles of socks for him from you folks, and all are great. Your socks have flat seams, and the elastic is not tight. I have no problems letting friends of ours about them. Please let other people who may need a warm sock and have problems with circulation in their feet know how great these are.

Jean (Rochelle, US)
soft and comfortable

Very well made socks. I sized up to avoid pressure on my toes but they still fit well and stay on. I gave four stars because they are not bison wool but they are still very nice. I would recommend these socks to keep your feet warm at night.

Morris C. (Boydton, US)
Great product and will buy more!

Bought for daughter who is always cold; she wore them that night!

Steve S. (Sacramento, US)
Sleeping socks were a big hit!

Was a small gift for Mothers Day and really well received! Too warm in summer here in Northern California but know they’ll be out of the drawer in fall!

Allison C. (Ludington, US)
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!
