Why people appreciate alpaca wool:
Alpaca fleece is soft, durable, and silky. The fibers are similar in size Merino wool, but they are mostly hollow, whereas sheep’s wool has pockets of air. It is the air pockets that trap heat, so alpaca fleece can be perceived as being warmer than Merino. Alpaca fleece is also naturally water-repellent. Because it does not absorb water at all, it retains its warmth even when wet. For those who may be sensitive to lanolin, which is naturally found in sheep’s wool, alpaca is a good alternative hypoallergenic fiber.
