01
Baby Alpaca (Under 22 Micron)
The first shearing of a young alpaca, or the finest fiber sorted from an adult clip — typically 18–22 micron. Noticeably softer than standard alpaca, comparable to fine merino in next-to-skin comfort. This is the grade that justifies premium retail ($180–$300+) and the one US brands typically mean when they say "alpaca sweater." Huacaya type (crimped, denser) is more common; suri type (silkier, longer staple) is available at a premium.
02
Suri Alpaca
Suri fiber has a long, silky staple with natural luster — it drapes differently from huacaya, more like a wool-silk blend. It produces a smooth, shiny surface rather than the slight halo of huacaya alpaca. Less common and slightly more expensive. Suited to drapey silhouettes (longline cardigans, wide-leg adjacent knitwear) where the surface shine is an asset. Knits differently than huacaya — tension and stitch structure need to account for its lower crimp.
03
Standard Alpaca (22–26 Micron)
Adult alpaca fiber from mature animals — slightly coarser than baby alpaca, more affordable, and appropriate for midweight structures at mid-market retail ($80–$160). Can be itchy at the neck for sensitive wearers — design should account for this with rib detailing or collar treatment. Often blended with merino to improve softness and reduce cost while maintaining the alpaca character.
04
Alpaca-Merino Blend
Combining alpaca (typically 50–70%) with extra-fine merino produces a yarn that's softer than standard alpaca, more durable than pure alpaca (alpaca can be fragile at fine gauge), and more cost-accessible than pure baby alpaca. The merino adds crimp and elasticity — improving shape retention and recovery, which alpaca alone lacks. This is the most practical starting point for brands new to alpaca sourcing.
