Alpaca fleece is the natural fiber harvested from an alpaca. It is light or heavy in weight, depending on how it is spun. It is a soft, durable, luxurious and silky natural fiber. While similar to sheep’s wool, it is 7x warmer, not prickly, and has no lanolin, which makes it hypoallergenic. Alpaca is naturally water-repellent and difficult to ignite.
