NATURAL HIGH-PERFORMANCE

Sweat-Wicking 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.

LOW ENVIRONMENTAL IMPACT

Eco-Friendly Boxer Briefs

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 Were These Boxers 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.

I'd prefer a boxer style

Soft, excellent light layer but a bit tight around legs & crotch due to design. I'd prefer and would buy boxer style underwear.

Can't believe it is (alpaca) wool

I get quite an itch from good 'ol sheep's wool, not so much with Merino, and none at all with these alpaca underwear.
They fit great (usual underwear size), and eerily don't smell after several days use.
100% satisfied thus far with my 100% alpaca wool underwear.
Be aware, there are other places that sell alpaca wool apparel, but this is the one place that I found that sells 100% alpaca wool.

<30 miles of hiking, completely disintegrated

I purchased two pairs of these briefs to wear on alternating days while hiking the Pacific Crest Trail and was excited for their softness and the natural fiber's ability to reduce odor. However, within 60 total miles, both pairs were completely useless.

The fabric rubbing between my legs eroded away almost immediately; I noticed the holes at Mile 30, so likely they didn't even last that long. By mile 60, both were completely useless.

Nothing on the company's website suggested the briefs would be ill suited for backpacking; in fact, in multiple places, Arms of Andes promotes the briefs as "The Perfect Underwear for Hiking", saying also that they are "designed for backpacking". Clearly not.

For further insult, Arms of Andes has determined that my case is not eligible for refund or other compensation. I'm not sure what conditions would have to exist for them to consider a product failure their own fault, but this seemed a cut-and-dry incident to me.

So now, I'm out $80 within a matter of days and have no refund with which to purchase replacement briefs. It's frustrating the product was so poorly suited for backpacking, but it's insulting that the company won't stand behind their product. Their customer service has been receptive to feedback but has stonewalled any requests for reimbursement.

Hi Jacob,
Thank you for taking the time to share your detailed feedback!. We’re truly sorry to hear about your experience, and we completely understand how frustrating and disappointing this must have been, especially during such an important trip like hiking the Pacific Crest Trail.
While alpaca fiber has many incredible natural qualities, including softness, breathability, and odor resistance, we understand that it may not always perform as expected under intense friction and long-distance backpacking conditions. We sincerely regret that the briefs didn’t hold up the way you needed them to.
We also apologize for how the outcome of your customer service experience made you feel. That is never our intention.
We value your trust and support and truly wish this situation had gone differently.

Nice but thin

I like the feel and sizing but the part by the bottom middle seam (lower crotch) has worn away and holes have appeared after about 10 wears. Other pairs are holding up with the same use.

Hi Ethan,
Thank you for your feedback, and we're really sorry to hear about the issue with that item. That’s definitely not the experience we want you to have, especially when you’ve been enjoying the feel and fit overall.
We appreciate you letting us know, and we’ll be sure to pass this along to our product team.
Thanks again for your support and for helping us improve!
