Care for your layer

Hand wash or machine wash on a gentle/wool cycle in cold water (50-68°F). Use a mild wool-safe or pH-neutral detergent. Wash with similar colors. Don't bleach or use fabric softener.

Reshape while damp and lay flat to dry. Don't tumble dry, twist, or wring. Cool iron if needed. Store folded in a cool, dry space with airflow; avoid hanging.

Naturally dyed colors can transfer with sweat or friction. Wear them with dark clothing or equipment, wash sparingly, and avoid citric acid, which can lighten the color.

Women's Alpaca Wool Long Sleeve T-Shirt: 160 Ultralight

The benefits

Why Alpaca wins

Alpacas en los Andes peruanos

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.

Very slim cut

I haven’t worn it yet so I can’t compare it to merino wool but the fit is Extremely fitted. I had to size up 2 sizes which then made the length very long

Itchy

Itchy and runs small. Not soft

Hi there! Thanks for sharing your feedback. We're always working to improve both our products and service, so input like yours is invaluable.

Regarding softness and itchiness: alpaca wool is naturally soft and hypoallergenic for most, but we understand that individual sensitivity can vary. Regarding sizing: our garments are designed with a slim/functional fit, so sizing up is always a great option if you prefer a more relaxed feel. Both our size guide and fabric care information are available on the product page.

That said, we'll absolutely take your comments into consideration as we continue to evolve our offerings, comfort and sustainability should always go hand in hand. We hope we have a chance to serve you better in the future!

Love the shirt but doesn’t last long.

Washing makes it look quite worn. For the price the material Should hold up better.

Second purchase

After buying two short sleeve V-neck ultra-lightweight tees I decided I needed a long sleeve one for cooler days, for under my flannel shirts. Arms of Andes are well made, comfortable and a perfect base layer for cooler temps. Being an older adult, I appreciate the comfort and temp regulating properties of the alpaca wool fabric.

Hi Karen, thank you so much for your continued support, we’re truly grateful you came back for another piece. It’s wonderful to hear that you’re enjoying the comfort and temperature-regulating qualities of the alpaca fiber. We really appreciate you sharing your experience!

Nice hiking shirt

Though I have not had a chance to hike in this shirt, I do find it fits and drapes well and the fabric texture looks very nice. After washing it I found it still itches a little bit so will try soaking it in vinegar to relax the fibers. Other than that I really love the shirt. Customer Service has been extremely helpful and answers inquiries quickly. I would definitely purchase again.'

Love it!

I have this is two colors and I love them. Easy care. Wash and lay to dry and they dry quickly. I can wear them several times before washing, which is easy, too.

Like a second skin

The long sleeve t-shirt makes a great base layer. I thought it looked too small when I took it out of the package but it is just right for a base layer, like a comfortable second skin. Thank you for making plastic-free clothing. I'd like to see natural alpaca colors (browns, gays, etc).

Women's Long Sleeve Wool T-Shirt

Great addition to my wardrobe. I have several colors now and wear these shirts alone and layer them under most of my tops for added warmth in during the winter months. They are so comfortable. I'm very pleased with the quality and grateful that they are 100% Alpaca.

Travel tested!

I was able to pack extra light on my last trip by bringing a couple of these tops. The trip involved trail running in the snow, relaxing by the fire, and a sauna. I brought separate alpaca t-shirts for running, sleeping, and daily wear. They kept me comfortable both inside and outside without getting stinky!
I have a 36" bust and 32" waist and bought size Small so I could layer the tops under sweaters. They also look nice enough to wear on their own, unlike a lot of layering tops.
PS I brought an alpaca tank top for the sauna!

Must have

I got this shirt in black and could wear it every day. I especially love how it regulates my temperature I don’t feel too hot or too cold while wearing it. Can’t wait to add more pieces like it!

Hi Tamiko, Thanks so much for the great review! We're thrilled you love the shirt and how it keeps you comfortable. Can’t wait for you to add more pieces too!

Great shirt!

I love my new shirt!! Soft, comfy, not itchy, a great shirt I will wear it all winter!! Must order more :)

Hi Kathy! Thank you so much! We’re so happy you love your new shirt, it’s perfect for staying cozy all winter!

Amazing top!

I am 5’6” and 125-129 lbs, and the S fits perfectly. It’s tight but not too tight, and I wear it either as a workout top or for work with a nice skirt or pants + jewelry to dress it up.

It’s comfy and the perfect temperature!

I’ve learned to hand wash my AoA clothes, and so they last. I don’t find the top itchy but I see how some could. Love the material.

Thank you for sharing your experience! We’re so glad the size and fit work perfectly for you, and that you’re enjoying the versatility for both workouts and dressed-up looks. It’s great to hear the material feels comfortable and that hand washing is helping your AoA pieces last. We appreciate your feedback!

Superb Quality

I am extremely satisfied with my long sleeve shirt. After just a few days of receiving my shipment, I ordered the same shirt in another color. I was nervous that the shirt would be too thin, but I think it’s perfect! I do feel the scratchiness that other people have commented on. However, the longer I wear it, the more comfortable I feel. Truly I feel like I’m receiving a gentle hug all day when wearing my shirt. I originally purchased this for a vacation since it doesn’t have to be washed often. I now realize that I will be wearing this all the time!! I’m so glad I found your company.

HI Jaclyn
Thank you so much for your lovely feedback! We're thrilled to hear that you're enjoying your long sleeve shirt and that it’s become a favorite. It means a lot to us that you came back for another color! We're so happy you found us too, and we look forward to keeping you comfy on all your adventures.

So nice!

The ordering process was easy; shipping was fast and good. The company is great. The sweater is the best I've tried -- alpaca is warmer and softer than merino; the weave of the fabric is naturally stretchy, so the fit is very comfortable. I'm an old lady - nearly 80! - and this is my favorite sweater. Wish it came in some other colors, but the black is timeless and goes well with jeans and with dress pants. I'd recommend Arms of the Andes and their products to friends & family.

Hi Nana,
Thank you so much for your wonderful message! We're thrilled to hear that you had a smooth ordering experience and that you're enjoying your alpaca sweater it truly means a lot to us.
It’s especially heartwarming to know it’s become your favorite! Alpaca really does offer that perfect mix of warmth, softness, and comfort, and we’re so glad it’s a great fit for you.
We appreciate your kind words and your recommendation

Not happy
Scratchy and uncomfortable

Don’t buy this. It’s incredibly uncomfortable. I wore it for the day to see if it got better and it didn’t, only to find out wearing it one time means you can’t return it. Can’t be washed either.
Just don’t buy this. There are other brands that are comparable prices that are sustainable and actually comfortable, unlike this one.

If you do buy it: Do not wear, do not wash. Or you’re stuck with it regardless of how you feel about it. But just save yourself some time and buy from a different brand. My partner bought theirs on paka and it’s much nicer than what I got here

Hi there! Thanks for sharing your feedback, we’re truly sorry to hear the item didn’t meet your expectations. We’re always working to improve both our products and service, so input like yours is invaluable.

Regarding returns: our policy does ask that items be in original, unworn, unwashed condition so we can responsibly give them a second life through reuse. This is outlined in our return policy on the website.

That said, we’ll absolutely take your comments into consideration as we evolve our offerings, comfort and sustainability should go hand in hand. We’re glad to hear your partner found a product they enjoy, and we hope we have a chance to serve you better in the future.

Begrudgingly wearing

Bought for my girlfriend who is getting into natural fabrics, particularly alpaca. She picked this brand because it was the only one with 100% alpaca.

She wear XS/S and was originally going to buy S but realized this fits tight and she is trying to lose weight so she felt she'd look bad. For reference she is still small but has a bit of tummy and doesn't like tight fitted things right now. Instead she got an XL to be safe. I think she should have gotten a M at most L. XL ended up being very roomy. I offered to exhange for a L but she didnt want me to pay for an exchange so she kept the XL. She also found out alpaca tends to stretch out over time so I think M would be best.

It doesn't look bad on her but isn't not great either, her words. She said it's itchy and after soaking for 16 hours in conditioner said it only moderately helped and is still itchy. All in all I don't think she is happy, but also knows how expensive this is, she got 3 different shirts, so she is trying to hide her disappoint. I don't forsee her asking for anymore alpaca or wool that she can't feel in person first.

Very nice base layer

I wore my 160 weight long-sleeve shirt over a very thin next-to-skin layer for two days on an overnight winter camp. It was a little itchy now and then, but overall it felt comfortable and cozy. The weight is perfect for a base layer and the navy color is beautiful and not see-through. I purchased a medium and I am 5'3" and 125 lbs, average chest and it fits perfectly. I didn't give it five stars only because I don't know about longevity and wool can be susceptible to holes.

We are happy you enjoy your garment. Always looking to make the best for you :D

A little tight

This will be good for a base layer but a little too snug on its own. Not quite as soft as some wools. Very thin, but strong and stretchy

Amanda
Awesome!

I have worn the t-shirt, long sleeve and long sleeve hoodie and have really enjoyed all of them. So far it has been for daily wear (and once to the gym) in winter in Michigan. I plan to use these on my month long hike in the UK this summer. The weight is great for layering and I haven’t washed any of them yet but are smell free. I love the athletic fit! I got the small in everything and love it (32DD, athletic build, 135lbs). They are a little itchy but I don’t notice it so much as the day goes on. Also im not sure how they will hold up under a backpack strap rubbing all day but that will be tested this summer. I am very please with these products!

Super warm, thin, and cozy

This long sleeve shirt is incredibly warm while being lightweight. It's everything you'd want in a base layer. The fibers are smooth and not itchy. This shirt can be worn for several days without smelling, so great for camping / travel purposes. The medium size fits me perfectly, I am 5'6", 125lb with a 35" bust. I recommend washing with Outback Gold wool wash.
