NATURAL HIGH-PERFORMANCE
The Lightest Thermal Base Layer
For thousands of years, alpacas have been adapting to extreme environments of the Andes Mountains, where temperatures range widely. The harsh highland conditions created the ultimate outdoor fiber, designed to keep you protected, clean, and comfortable.
Designed for the Outdoors
- Perfect Temperature
Semi-hollow fibers act as an internal A/C, balancing your body temperature in extreme climates. - Always Dry
High moisture-wicking fibers keep your body and clothes dry and sweat-free all day. - Clean & Fresh
Naturally anti-bacterial & odor resistant keratin fibers ensure your hygiene.
Go Further, Pack Lighter

- Light & Durable
Semi-hollow core fibers insulate and make the fabric lighter and resistant. - Wear More, Wash Less
Alpaca dries quickly and absorbs minimal moisture, preventing bacterial growth.
Luxurious Softness
- Smooth Fiber Scales
The scales of alpaca fibers are smoother than those of sheep wool. They help wick moisture away, while also having incredibly low moisture absorption. - 18 to 19 Microns* Alpaca Wool
The finest Alpaca Wool with naturally smooth fiber scales minimize felting and ensure luxurious softness on your skin without itching.
*Microns define the diameter of the fiber.

Zero Microplastics & Toxic Chemicals
We created 100% plastic-free and biodegradable shirts so that you can wear your clothes knowing that you are not releasing any microplastics.
Microplastics are not only found in the environment but also in our bloodstream.
Our naturally dyed shirts contain zero synthetic dyes and we are looking for a natural replacement for the silicone fabric finishing.
Our wool is never Superwashed since alpaca fibers are naturally smooth.
Free-Roaming Andean Alpacas
Alpacas roam freely in their natural habitat in the highlands of Peru. Their farmers never harm or kill them for their wool. Alpacas create small footprints that do not damage the fields they graze on. When they eat, they cut the grass, promoting regrowth.

SINGLE ORIGIN SUPPLY CHAIN
Where Was This Base Layer Made?
We use natural local resources and a short transparent supply chain. Our mission is to teach you as much as possible about how clothes should be made. Together we can move the fashion industry towards a sustainable future.
Designed & Made in One Country: Peru
Contrary to industry norms, every step involved in making our clothes is done in only one country: Peru, the home of our family. Our production in Peru includes fiber sourcing, yarn spinning, fabric knitting, dyeing, finishing, and garment sewing.
From Peru, our clothes go straight to California or Europe on its journey to you.
Low Carbon Footprint
Manufacturing in one country allows us to greatly reduce our carbon footprint and freight shipping. This is a major step on our journey to becoming a carbon negative company.
Transparency & Traceability
We avoid industrial farming by working with co-op farmers in the Andes. Doing everything in Peru guarantees we know how the alpacas and the workers involved are being treated.
