The pattern was inspired by vintage Nordic sweaters , and the itchy material , originally made from sheep 's wool for food , was replaced with baby Thule alpaca. Thule alpaca is a rare material made up of extremely fine fibers from the Thule variety of alpacas that live in the Andes Mountains in Peru , which are over 4,000 meters above sea level , and only 3% of all alpacas live there . Each strand of this yarn is extremely fine , so it is very soft and gentle to the touch , and is light and warm . The 3G low gauge finish makes it look heavy , but it is light and comfortable to the touch, and the jacquard pattern is deliberately turned inside out to convey the brand's message of removing various boundaries .
