Fabric Definition:
Yak wool is a soft, warm, and highly durable natural protein fiber harvested from the undercoat of the domesticated Yak, prized for its exceptional thermal insulation, incredible softness, and sustainable Himalayan origin.
Composition:
100% Keratin (Protein) – fine undercoat (khullu), typically 14-20 microns; hollow core, lanolin-free
Texture:
Incredibly soft (comparable to cashmere), warm, with a natural crimp, slight luster, and a dry, clean hand; finer grades are downy and luxurious
Stretch Level:
Low (Natural springiness gives some give; spandex blends add performance stretch)
Fabric Construction:
Woven (e.g., Yak Suiting, Gabardine) or Knitted (e.g., Jersey, Rib, Chunky Knits)
GSM Range:
150-600 GSM (Light for base layers, medium for sweaters, heavy for outerwear and blankets)
Breathability:
Excellent – Highly breathable, excellent temperature regulation, wicks moisture effectively
Moisture Management:
Excellent – Hollow fibers absorb and release moisture, keeping skin dry and comfortable in extreme cold
Durability:
High – Durable and resilient, with good abrasion resistance; coarser outer hairs are removed, leaving only soft down
Thermal Properties:
Exceptional – Superior warmth-to-weight ratio; significantly warmer than sheep wool, excellent for cold weather
Key Usage Areas:
Luxury Knitwear (Sweaters, Cardigans), Outerwear (Coats, Jackets), Accessories (Scarves, Hats, Gloves), Blankets, Throws, Baby Clothing, High-End Suiting
