Alpaca Wool

Our products are made of alpaca wool and natural cotton.

All products are imported from Lima, Peru. But what’s so special about alpaca fiber?  It’s extremely warm, is the strongest mammal fiber, light weight, and very water resistant.  It has other qualities, as well. Alpaca has some medullated fibers: in other words, there are tiny hollow pockets in the centers of many individual alpaca fibers. These areas hold the warmth. 

Alpaca is very water resistant. Gaston College’s representative told the Alpaca Fiber Symposium that their tests showed alpaca to be virtually water repellent.
They found it all but impossible to saturate alpaca fiber to do the test. (Sheep’s wool absorbs up to 35% of its weight in water.
