NATURAL HIGH-PERFORMANCE

The Lightest Thermal Leggings

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

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.

Leggings

Love what I received. In love with alpaca. Wish I could afford more. Would have given 5 stars but not sure of its durability. First items I tried seem to be a bit flimsy and fragile. Still using some even with holes.

Hi John,
Thank you so much for your honest and thoughtful feedback.
We’re so glad to hear you love what you received and are enjoying the alpaca!
We totally understand your concerns about durability. Alpaca is incredibly soft and luxurious, but it can feel more delicate compared to synthetic blends. We really appreciate you sharing your experience, and we’ll be sure to pass this along to our product team.

Seems good

I'm a waist 32 and XL size fits snug. I might order XXXL next time just cuz I have swollen left foot/lower leg. Low but noticable itchiness, especially behind knee. I'll be searching for loose underlayers if available. Probably perfect for sporty needs. seems warm but not as warm as expected.

Hi there,
Thanks for sharing your feedback! We appreciate your insights on the fit and warmth. If you’re looking for a looser underlayer, feel free to reach out—we’d love to help you find the best option for your needs. Hope you stay warm and comfortable!

Fantastic base layer/leggings

Bought for an upcoming trip to the arctic, but I've been wearing them around the house and around town to try them out. They are really comfy and warm. I can't wait to run around with the reindeer with these keeping me warm. My only problem is I need to buy a pair in Medium for my travel partner and they are sold out.

Hi Matthew,
We're so glad to hear you're enjoying the comfort and warmth of the leggings! Sounds like they'll be perfect for your Arctic adventure. We hope to have the medium size back in stock soon. Thanks for your patience, and we hope you and your travel partner stay cozy and warm on your trip!
