The Fiber Science

Softer than merino. Warmer than cotton.

"Isn't yak wool scratchy?" is the question we hear most before someone tries a pair. It isn't — here's why, measured in microns, not marketing.

  • Fine down fiber, not coarse guard hair
  • Comparable softness to cashmere, better insulation
  • Naturally moisture-wicking and odor-resistant

Care Guide

One hot wash is all it takes to ruin them.

Natural fiber needs different care than cotton. Cold water, no dryer, dry flat — three rules that make a $24 pair of socks last years instead of months.
