What are the main reasons for wearing an alpaca wool beanie ? A beanie must be warm and protect us from the cold, it must not itch if you want to wear it all day, it must also stay in place if for example you put it on for sports. All these qualities, alpaca wool, with its unique properties, can bring them to you. Our beanies are made by Peruvian knitters from baby alpaca wool, the finest fiber in alpaca, and recognized as one of the most beautiful in the world.
