From mYak:
"Baby yak is the bedrock of our company. Touching worsted-spun baby yak down is a unique experience: a precious fiber that creates a fabric different from anything else you have ever knitted before. Worsted-spun baby yak down yarn is a luxury fiber that will yield a fabric unlike anything you have knit before. Baby yak has a similar micron count around 17 microns to cashmere. It is warm and lustrous, lightweight and breathable, making it perfect through the seasons.
Our baby yak colors are soft, heathered, earth tones combined with dark neutrals and few saturated rich ones. Most yaks are of darker shade, and thus light colors are very rare and even more precious. Warmer than wool, and as soft as cashmere, our 100% baby yak is the right choice if you are looking for a unique, ethically sourced fiber good for you, for the environment and for the community that produce it.
We only dye on the natural basis, no bleaching or decoloring. Each color will vary from season to season depending on the shade of the natural fibers, making it at times darker and at times lighter. This is the beauty of working with natural fibers and therefore the shade of the sample you see photographed here, might not always correspond to the shade we have in stock or at your local LYS."
