Alpaca vs merino: alpaca is usually warmer, fluffier and has a soft halo, so it shines in cosy sweaters and cardigans. Merino is finer, smoother and easier to wash, so it wins for base layers, tees and travel. Many brands blend the two to get warmth and softness with less itch.
Quick answer
Choose alpaca for warmth and a fluffy, cosy knit; choose merino for next-to-skin comfort, everyday wear and easy care. Blends combine both.
Key takeaways
- Alpaca: warm, lofty, often has a halo; many pieces are dry clean or hand wash only.
- Merino: fine, smooth, breathable; many pieces are machine washable on gentle.
- Both are natural animal fibres that need cool water and flat drying.
- Blends (alpaca + merino + nylon) trade a little softness for durability.

What do indie brands make in alpaca?
Christy Dawn makes many of its knits in alpaca or alpaca blends. Its Forever Cardigan, for example, is listed as 100% alpaca, yarn dyed with organic dyes, hand knitted in Peru and eco dry clean only. Read more about the label in our Christy Dawn brand spotlight.
Toad&Co blends the two fibres. Its Toddy T-Neck Sweater uses a fuzzy yarn listed as 47% nylon, 35% non-mulesed wool, 15% alpaca and 3% elastane, which the brand describes as warm but never itchy. Our Toad&Co brand spotlight has more.
What do indie brands make in merino?
Unbound Merino’s Women’s Merino Fisherman Sweater is listed as 100% ultrafine merino at 17.5 micron, with care instructions to machine wash cold on gentle, inside out in a laundry bag, and lay flat to dry. wool& uses merino blends for everyday dresses and tees; see our wool& brand spotlight.
Which is better for sensitive skin?
Comfort depends on fibre diameter and how the yarn is spun. Fine merino (around 17.5 to 19.5 micron) is widely chosen for next-to-skin wear. Alpaca has no lanolin, which some people with wool sensitivity find easier, but its halo can tickle. If you are unsure, try a blend or wear a thin layer underneath.
How do you care for alpaca and merino?
- Follow the label first. Many alpaca pieces say dry clean only; many merino pieces allow a cold gentle machine wash.
- If hand washing, use cool water and a wool wash, then dry flat. Our wool sweater washing guide walks through it.
- Remove pills gently with a comb; see our de-pilling guide.
- Store folded with cedar to deter moths, as in our sweater storage guide.
