Yak Wool
Fiber from the downy undercoat of yaks. Warmer than merino, softer than cashmere of the same grade, and more sustainable.

What this score doesn't measure
This is a material rating, not a verdict on any specific garment made from yak wool. The axes above are research-backed averages for the fiber itself.
- ×Construction. Yarn staple length, weave / knit structure, stitch count, finishing. Identical fiber, very different garments.
- ×Fabric weight (GSM). A 140 GSM tee and a 220 GSM tee made of the same yak wool feel and last very differently.
- ×Dye + finishing chemicals. Beyond the three we flag (PFAS, formaldehyde, antimony), dozens of textile finishes aren't modelled.

Care Guide
Special Notes
• Similar care to cashmere
• Reshape while damp
• Naturally odor-resistant
Additional Care Tips
- • Hand wash in cold water (below 30°C) with wool-specific or pH-neutral detergent
- • Never wring — gently press out water between towels and reshape while damp
- • Lay flat to dry on a mesh rack away from direct heat or sunlight
- • Store folded with cedar or lavender sachets — never hang, as yak wool stretches
- • Avoid fabric softener and bleach — they damage the delicate down fibers
- • Wash infrequently — yak wool is naturally odor-resistant; air out between wears
