Vicuña
A
The rarest and most expensive animal fiber in the world, from the vicuña of the Andes. Finer than cashmere, incredibly soft, warm, and lightweight. A single coat yields only 250g of usable fiber every 2-3 years.

What this score doesn't measure
This is a material rating, not a verdict on any specific garment made from vicuña. 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 vicuña feel and last very differently.
- ×Dye + finishing chemicals. Beyond the three we flag (PFAS, formaldehyde, antimony), dozens of textile finishes aren't modelled.

Special Notes
• Extremely rare and expensive — professional care recommended
• Hand wash with utmost care if not dry cleaning
Additional Care Tips
- • Professional specialist dry clean only — standard dry cleaners may damage the delicate fibers
- • Never machine wash, hand wash, or expose to water
- • Store in acid-free tissue in a cedar-lined or climate-controlled closet
- • Use a cashmere comb very gently to remove pills — the fibers are finer than cashmere
- • Keep away from perfume, moisture, and direct sunlight
- • Handle as little as possible — oils from hands can damage the ultra-fine fibers over time
