NATURAL HIGH-PERFORMANCE

Moisture-Wicking Shirt

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.

Love what I received. Hope they last better than last ones. Sized up seems to help. Just seems like better quality than last ones. Had problems with colors. This time only have dark ones.

Hi John,
Thank you so much for your feedback. We’re really happy to hear you’re loving what you received this time around!
Sizing up can definitely make a difference, and we're glad to know this batch feels like an improvement in quality. We also appreciate you sharing your past experience with the colors going with darker tones is often a great choice for longevity.

Alpaca is amazing!

I've been wearing this almost daily, as a base or on its own. The workmanship is flawless: smooth seams, sleeves long enough to reach my hands, the sizing is perfect (I went up a size for relaxed fit). I'll highly recommend Arms of the Andies.

Hi Steven,
Thank you for your kind words! We're so glad to hear that you're enjoying your piece daily and that the fit and craftsmanship are just right for you. We truly appreciate your recommendation and support!

Incredibly Comfortable

It's one of the most comfortable shirts I've ever worn. I hand-washed my shirt first in a very gentle soap, which makes all the difference for those who complain of itching. I wear my shirts daily to keep warm during these cold New England days and nights. Thank you, AofA, for such an incredible product!

Hi Thomas,

We're so happy to hear you're loving your shirt! It’s great to know it’s keeping you warm through those brisk New England days. Thanks for sharing your experience and for being a part of our community!
