Alpaca vs. Cashmere vs. Merino Wool: Which Is Best?
By the Alpaca Atlas team · Updated
Fine alpaca is comparable in softness to cashmere and merino, tends to be warmer for its weight, contains no lanolin and often pills less than cashmere. Cashmere is usually the softest and most expensive; merino is the most versatile and easiest to care for. The best choice depends on how you'll wear it.

When to choose cashmere or merino
Cashmere is hard to beat for pure softness and a fuzzy, cozy look, but it usually costs more and tends to pill. Merino is the practical choice for activewear and base layers, and many merino garments tolerate a gentle machine wash.
Frequently asked questions
- Is alpaca warmer than cashmere?
- Alpaca is often described as warmer for its weight because many alpaca fibers are partly hollow, which traps air. In practice, knit thickness matters as much as the fiber.
- Is alpaca more durable than cashmere?
- Alpaca fibers are generally longer and stronger than cashmere, so alpaca knits often pill less and keep their shape well with proper care.
- Is alpaca good for people with wool allergies?
- Alpaca contains no lanolin, and many people who react to sheep's wool find alpaca comfortable. If you have a diagnosed allergy, check with your doctor.
