Alpaca fiber comes from the fleece of the animal bearing the same name. Alpacas are mainly bred in the Peruvian Andes. Alpacas are much more eco-friendly than cashmere goats, because they cut the grass they eat instead of pulling it out, which allows for the grass to keep growing. Additionally, Alpacas have soft padding under their feet, which is more gentle for the soil than goat or sheep hooves.
They need very little water and food to survive and produce enough wool for 4 or 5 sweaters per year while a goat needs 4 years to produce just one cashmere sweater.
