NATURAL HIGH-PERFORMANCE

The Lightest Wool Long Underwear

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.

  • 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.

Alpaca Wool is lightweight and does not require frequent laundering, letting you explore 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.
  • 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.

ALPACA WOOL: FIBER OF THE GODS

The Superior Fiber for the Outdoors

Alpaca wool is a superior choice for the outdoors and outperforms any other fiber: merino wool, cotton, rayon and polyester.

THE COMPARISON: ALPACA VS OTHER FIBERS →

LOW ENVIRONMENTAL IMPACT

Eco-Friendly Leggings

When wearing 100% Alpaca Wool, you can rest assured that your clothes are not contaminating nature.

  • 100% Alpaca Wool Fabric
  • 100% Cotton Threads
  • 100% Organic Cotton Labels
  • 100% Natural Dyes or OEKO-TEX Certified Dyes
  • OEKO-TEX Certified Silicone Fabric Finishing
  • GOTS Certified Ink (for the labels)

We are on a journey to create 100% plastic-free and biodegradable bottoms 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 bottom layers contain zero synthetic dyes and we are looking for a natural replacement for the silicone fabric finishing and waistbands.

Our wool is never Superwashed since alpaca fibers are naturally smooth.

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 Were These Leggings 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.

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.

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.

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.

This is my first alpaca piece and I'll never go back to merino. I wanted relaxed fit and the specs are spot on. Great fit, breathable, and so soft... my wife tried this on and will be ordering for herself. No better recommendation than that!
