Peruvian Alpaca wool is lightweight, breathable and very soft. Alpaca is naturally hypoallergenic and contains no oil or lanolin. Because Alpaca wool does not contain natural wax lanolin, it does not itch, unlike sheep wool; it is full of this natural grease that is rubbing against your body and as a result create that itching. The wax can be so irritating that it can also cause allergies for some people. As alpaca does not have lanolin in it.
