LEARN MORE ABOUT ALPACA PERFORMANCE

MOST SUSTAINABLE BASE LAYER

Alpacas roam freely and happily in the highlands of Peru, where nature intended. Their farmers never harm or kill them for their wool. Alpacas live in their environment well, they have small footprints that do not damage the fields they graze on. When they eat, they cut the grass, promoting regrowth.

Alpaca fibers are naturally smooth, we never superwash! Superwashed wool is usually treated with harsh chemicals to remove natural scales. This process adds to contamination and may affect the fiber's performance. We leave our Alpaca's fiber as is, with no chemical alteration.

When wearing 100% Alpaca Wool, you can rest assured that your clothes are not contaminating while outdoors or when washing. We only use biodegradable Alpaca wool in our fabric, protecting our environment.

ROYAL ALPACA WOOL FLEECE

Alpacas are adapted to extreme environments and naturally developed a unique fiber structure. Found in the center of their fiber are hollow & semi-hollow spaces that insulate, while also being strong and light. The scales of alpaca fibers are smoother than those of sheep's wool. They help wick away moisture, while also having incredibly low moisture absorption.

Alpacas have been living in the Andean Mountains for millennia. They are found up to 15,700 feet (4,800 meters) high in the mountains. Here, the temperatures range widely, from very hot and strong sunny days to ice cold nights. Over the years, alpacas have adapted to these extreme conditions, developing a unique hollow core fiber, not common to other species. The local communities valued alpacas for their fiber and the Alpaca soon became part of the Andean culture.

Alpaca wool is the superior choice for the outdoors, above merino wool, cotton, rayon, and recycled synthetics. Click below to learn how our alpaca clothing outperforms other fabrics.
