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.

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.

LOW ENVIRONMENTAL IMPACT

The Most Sustainable Shirt

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 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.

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 Shirt 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.

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.

Warm & comfortable

Comfortable, breathable, wool warm, . Hood blocked wind.

Hi there,

We're happy to hear you're enjoying the warmth and breathability! The hood is definitely a great feature for blocking the wind. Thanks for your feedback!

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!

Love it

Was very fortunate to win this along with matching leggings. 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 :)

Hello Jeff,
What a great win! We’re so glad the set worked out perfectly for those chilly nights. It sounds like it’s a game-changer ! Thank you for sharing your experience, and we hope you enjoy them for many cozy nights ahead!

I love the warmth and feel

I'm about 6' with long arms and the L fits well. I machine washed and dried flat with no deviation. Love it!

Hi Manuel,
That's awesome to hear! We're so glad the L fits well and that you're happy with the quality. Thanks for sharing your experience, and we're thrilled it's working out perfectly for you!
