Alpaca fleece is light weight or heavy weight, depending on how it is spun. It is soft, durable, luxurious and silky natural fiber. While similar to sheep’s wool, it is warmer, not prickly, and has no lanolin which makes it hypoallergenic. Alpaca is naturally water-repellent. Huacaya, an alpaca that grows soft spongy fiber has natural crimp, thus making a naturally elastic yarn, perfect for knits.
