The benefits

Why Alpaca wins

Andes-adapted for changing temperatures

Alpacas evolved where days run warm and nights turn cold. Their semi-hollow fibers trap insulating air, helping you stay comfortable as the temperature changes.

Softness starts in the fiber

Alpaca’s smoother scales give the fabric a soft feel against your skin. Comfort comes from the fiber’s structure.

Wear more, wash less

Alpaca wool naturally resists odor. Air your layer between wears, then wash it when it needs cleaning. Less time doing laundry. More time outside.

Single origin

Peru, start to finish.

Arms of Andes is a family company with roots in the Peruvian Andes. “Arms” brings together the initials of four siblings. That connection to Peru shapes what we make and where we make it.

From fiber sourcing and yarn spinning to knitting and sewing, production stays in Peru. One country, with the people and knowledge behind your gear close together.

Customer reviews

Terrible firm to deal with, because of their return policy. I ordered an item that was too large, sent it back, and they refused to credit my account because of "wear and tear." I had "worn" it all of the two minutes it took me to try it on and determine it was too large. They did not return the disputed item to me, but are trying to keep my money anyway.

The item was of acceptable quality, but I simply refuse to do business with a firm that won't accept returns; it puts ALL the risk on the customer to trust that their sizing charts are correct, when anyone who shops online knows that this often (as here) not the case.

Since, I've been inundated with all sorts of their marketing crap, even though I specifically told them in writing to remove me from all future correspondence. Very unsatisfactory, from now on I'm sticking with Alpacas of Montana.

Hi Kurt, we’re very sorry for your experience. We do want to clarify that we can’t accept returns on items that show signs of use, as stated on our website, and the item you sent back was received in used condition. You’ve already been informed that it’s being sent back to you, and you were notified about this. We understand your frustration and appreciate your feedback.

Definitely worth it

Love the fit Love the feel. I must agree with some of the other reviews,that the neckline is low cut.However I'll be using this for function not fashion.I wore it on a weekend ruck and it's just what I'm looking for. Highly recommend

Hi Michael,
Thank you so much for your feedback! We're glad to hear you love the fit and feel, and that it performed well on your weekend ruck! We appreciate you pointing out the neckline too it's helpful for others to know.
Thanks again for the recommendation!

Low Cut Neckline

The feel of the material is great and the fit is true. It is important to wash the garment before wearing otherwise it has a tendency to be itchy. The washing process softens the material making it feel luxurious. I wish the front neckline was higher. It drops so low in front it is almost uncomfortable to wear. I would still recommend this garment as long as the low neck line is OK.

Hi Alan, Thank you for your thoughtful feedback! We're so happy to hear you love the feel of the material and that the fit is just right. We appreciate your tip about washing before wearing, it definitely helps with that soft, luxurious feel! We totally get your point about the neckline, and we’ll make sure to pass that along for future designs. Thanks again for recommending the garment, and don’t hesitate to reach out if you have any other thoughts or questions!

Great t-shirt

Great tank, very comfortable.

Hello Stanley!
We're so glad you love the tank! Thanks for your kind words, and feel free to reach out if you need anything else.

Small neck cut WAY too low

as the title reads. the small neck cut is so low on me it barely even covers my chest making it mostly useless. super bummer as the leggings were awesome.

Hi Jack,
Thank you for sharing your feedback! We’re sorry to hear that the neck cut didn’t work for you. We're glad to hear you liked the leggings, though! Your input helps us improve, and we appreciate you letting us know.

Men's Alpaca Wool Tank Top

Order fulfillment took less time than initially predicted. The tank feels durable and well-made. Initially it was a bit itchy, but after a few washes/wears it softened a great deal. I have noticed that I can wear it several times before it begins to stink. It has quickly become my go-to undershirt.

Amazing tanktop

My new favorite tanktop. I have been wearing it every day, went back and immediately ordered more so I wouldnt have to wear the same one every day. A bit scratchy at first but after the first wash it is luxuriously smooth. Highly recommended, in fact I have recommended and shown it off to everyone I know.
