Aiayu's llama wool is sourced and refined locally in a factory in Bolivia that handles all production processes from fiber sorting, washing, carding, spinning and knitting of the final garment. The factory cleans and reuses its wastewater and runs solely on renewable energy.The llamas roam and graze freely in large packs in the Bolivian highland, contributing positively to nature's biodiversity. Its wool is our signature material and has exceptional properties: it is both soft very durable, pill-resistant, hypo-allergenic, self-cleaning, and extremely effective at insulation. A true natural wonder.Colours starting with 'pure' are all-natural and refined without the use of chemicals – Offered exactly as nature made them with every shade difference and perfect imperfection that this entails.
