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.

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

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.
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.

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.

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 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.

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.

Best Buy Ever

The Alpca long-johns that I purchased are super comfortable and warm. Highly recommend the purchase of this product!

Very happy.

Was very fortunate to win this along with matching long sleeve shirt. Very comfy and really helped in 25 to 35 degree nights (in a sleeping bag too) Got mine a size up because I prefer a slightly looser fit. Compared to regular long-johns with thicker material these beat them by thousands of miles. Will cherish these for as long as humanly possible.
Thank you :)

Hi Jeff!
How wonderful to hear you’re enjoying them! It sounds like they’re the perfect fit for those chilly nights. We’re so glad you won them and that they’re making such a difference. Thanks for sharing your experience, and here's to many cozy nights ahead!

Super comfortable

These are fantastic! They are very comfortable on the skin, no itching or anything like that. They keep my legs warm yet if you come inside, they don't cause your legs to overheat. They fit very well.

Hi Harold! Thank you so much for the wonderful feedback! We're thrilled to hear that you’re enjoying the comfort and warmth of the leggings. If you need anything else, don't hesitate to reach out!
