Alpaca
Fiber from alpaca fleece. Warmer than sheep wool, hypoallergenic, and naturally water-resistant. A sustainable alternative to cashmere.
Material Score Breakdown
7-axis material rubric, not a garment verdict — see disclosure below.
How long the fabric lasts with regular use
Softness, feel against skin, wearability
Air flow and ventilation
Heat retention and insulation
Ability to pull sweat away from skin
Environmental impact of production and disposal
How easy it is to wash, dry, and maintain
What this score doesn't measure
This is a material rating, not a verdict on any specific garment made from alpaca. 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 alpaca feel and last very differently.
- ×Dye + finishing chemicals. Beyond the three we flag (PFAS, formaldehyde, antimony), dozens of textile finishes aren't modelled.

+13 vs Alpaca · 92/100
BiodegradableThe 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.
+7 vs Alpaca · 86/100
BiodegradableUltra-fine wool from Merino sheep. Softer and less itchy than regular wool, with excellent temperature regulation and moisture management.
+3 vs Alpaca · 82/100
BiodegradableExtra-long-staple cotton historically grown in the West Indies (Barbados, Jamaica) and Sea Islands of Georgia/South Carolina. Among the rarest commercial fibers on earth — staple length up to 2.5", silky hand feel, intense color saturation when dyed. Used in heritage luxury shirting and bespoke menswear.
Care Guide
Special Notes
• Reshape while damp
• Naturally hypoallergenic — no lanolin
Additional Care Tips
- • Hand wash in cool water (below 30°C) with wool or delicate detergent
- • Never wring or twist — gently press water out with a towel
- • Lay flat to dry on a mesh rack, reshaping while damp
- • Iron on low heat with a press cloth if needed — alpaca is heat-sensitive
- • Store folded with cedar blocks to repel moths; avoid hanging to prevent stretching
- • Avoid fabric softener — alpaca fibers are naturally silky and do not need it
