Alpaca fleece is much like sheep’s wool, but warmer and not itchy. It is lacking in lanolin, which makes it hypoallergenic and also allows it to be processed without the need for high temperatures or harsh chemicals in washing. Alpaca is a specialty fiber that has been described as stronger than mohair, finer than cashmere, smoother than silk, softer than cotton, warmer than goose down and better-breathing than thermal knits.
