Alpaca Review: Arms of Andes

We tested a variety of clothing for this alpaca review, including hoodies, base layers and more, from Arms of Andes. Here's what we thought!

Are you interested in leaping into the exciting world of alpaca clothing?

In this alpaca clothing review, we tested clothing from Arms of Andes to see if it was worth the hype and cost. We'll also delve into what makes alpaca wool special, as well as some frequently asked questions about wearing it!

September 2024 update: This was originally a comparison post between two of our favorite alpaca brands. Sadly, Appalachian Gear Company seems to have gone out of business earlier in 2024. However, we still recommend their clothing, so if you can find it used or from a third party, it's a great find!

What’s the Deal With Alpaca?

The reason you might choose alpaca wool is a similar idea for wearing merino wool: it's a sustainable natural fiber that is naturally moisture wicking and odor resistant.

This makes it a compelling option for multi-day backpacking trips, like the ones we've taken on the Art Loeb Trail in North Carolina or the Elk Park to Needleton loop in Colorado.

We've been testing out some alpaca options over multiple seasons (hot and cold), and have been thoroughly impressed. We wore lots of alpaca on a recent backpacking trip to Iceland, and stayed both warm and dry.

How Does Alpaca Compare With Merino Wool?

On the pro side, it is even more odor resistant than merino. As in, almost mind-blowingly odor resistant. It also dries more quickly than the already quick-drying merino.

If you have an allergy to the lanolin in merino wool, alpaca may work for you since alpacas don’t produce lanolin.

What about cons?

Alpaca is definitely more delicate than merino. One of our Arms of Andes shirts got holes because of friction caused with a too-sharp belt buckle. One of the hoodies we tried got minor pilling on the fabric where it rubbed against a hiking daypack.

It's also more expensive than merino and – a biggie – can be MUCH itchier than merino. The itch factor varies a lot from person to person, but it’s definitely a thing.

We’ve also noticed that (in general) alpaca clothing seems to stretch out of shape more easily than merino.

Also, there are fewer companies currently producing alpaca clothing (compared to merino), so it can sometimes be difficult to find items in stock.

Arms of Andes Clothing Sizing

The men’s clothing seemed to run true to size. The long sleeve men’s shirt sleeves were long enough for my long-armed husband.

The women’s clothing seems to run small, at least one size smaller than average. If you carry weight in your stomach, it might seem like it runs even smaller, as the women's tops are a fitted cut.

I tried the women’s half-zip and women's t-shirt in large (one size larger than normal for me). Both fit well but were on the snug side.

However, I ordered my usual unisex t-shirt size from the men’s line: a men’s small. It fit perfectly. If the women's line seems too tight for you, try ordering a men's cut, one size smaller than your usual women's size.

So far we haven’t noticed significant stretching from this clothing line. There was minimal stretching, particularly around the neck opening, after multiple wears, but the garments seem to go back to their initial shape (or close to it) after washing.

Alpaca Review: The Look

This line could easily double as casual wear and does not have a distinctive “alpaca“ look. Some other alpaca wear we tried looked distinctively fuzzy.

I particularly love the Arms of Andes items as travel-wear, because I can use it both while hiking and while exploring a town without feeling either under or over-dressed.

Alpaca Review: The Feel

The base layer tops were in fact much softer than other alpaca tops we ordered for review, and less itchy! I'll still say they were SOMEWHAT itchy (to me) at first, but not unbearably so.

They reminded me of the texture in Icebreaker's merino base layer tops, but perhaps slightly softer.

The half-zip was extremely thick and soft! It would be a great top in frigid weather. The hoodies were the same weight as the half-zip, and were also incredibly warm yet breathable.

The boxers and undies (happily) were not itchy at all, and their extreme odor resistance makes them perfect for multi-day backpacking trips. (Because the fabric is a bit more delicate than merino, I'd hesitate to use these undies daily.)

Was It Comfortable in Both the Cold and Heat?

Yes! The ultralight shirts were incredibly comfortable and breathable in the heat.

Recently my husband wore the ultralight t-shirt on a 3-day backpacking trip in North Carolina, and found it comfortable even in the 90-degree heat. (Well, as comfortable as someone can be in 90-degree heat.)

I’ve also found the Arms of Andes ultralight shirts to be cool and breathable, even in the heat. I wore an Arms of Andes t-shirt recently on a day where the heat index reached 106 degrees Fahrenheit, with high humidity, and not only did it not feel too hot, but the shirt did not stink the next day! (And I definitely sweated.)

The ultra-light shirts also make perfect base layers in colder weather. The thicker half-zip and the hoodies are definitely a cold-weather items and not for heat.

Arms of Andes Items We Liked But Didn't Love

The leggings are more base-layer style as opposed to workout leggings. They're great as pajamas or as a base layer in very cold temperatures. They're also opaque enough to wear as casual-wear with a tunic top. However, I have noticed mild pilling between the legs after light wear.

The women's sports bra was the same comfortable fabric, but probably best if you're an A-cup (or possibly a B-cup), but definitely not any larger. It was not supportive and I absolutely would not wear it on a trail run.
