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 Leggings: 300 Lightweight

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.

I never received my item

Again, I’m still fighting with you to either get a refund or new merchandise because U still have not received this item and the neck gaiter I ordered which you charged m credit card for on 5/13.

You are severely failing in customer service; with each email I send you tell me you are waiting on your Amazon claim. Why should I our customer have to wait on my product which you charged me for 3 weeks ago while you work out your issues with Amazon and how silly that your asking me to review a product you KNOW I did not receive.

Ridiculous service and ridiculous company management.

Love them, I hope the moths don't

They stretch beautifully, so they fit better than some pairs of wool tights I wear. I'm afraid to follow your instructions about wearing them many times before washing them. Aren't moths more attracted to sweat and skin flakes than clean material? I launder out of fear.

Fits as stated, great feel, size medium

I was afraid they would be too tight, but they fit good as a medium for my 5'6, 122# frame. Was long enough which many other brands were not. Not scratchy, but you can feel the wool. Perfect weight, not hot. Good for chilly mornings. I can wear all day comfortably. Will recommend!

Thank you so much for sharing your feedback! It’s great to know you’re finding them comfortable for chilly mornings and easy to wear throughout the day. We truly appreciate the recommendation and your support!

Love them

This is my second pair. One to wear while one is being washed and dried. I hand washed them. They are absolutely odor resistant as advertised. And well made. So cozy and comfortable. Full disclosure, I have never been backpacking or winter camping. I do live in the central Colorado mountains.

Thank you so much for coming back for a second pair! We’re really happy to hear they’ve been working so well for you and keeping you comfortable!

Love these leggings!

This winter required extra warmth and these leggings were just what I needed. I wore them every day for two weeks as the temperature was below zero. They washed up beautifully. I would get a second pair if only my size were not out of stock.

Very comfortable, soft and warm

These leggings were a 'gift' from my wife as they were too long for her. I tried them on,,, fit me perfectly! They are a good weight for warmth, feel extremely soft and have kept me warm with or without outer wear depending on the weather. They allow for good freedom of movement without bunching up and the ankles stay put without undue constriction.
I give them an "A" plus

new winter favorite

winter in Michigan is cold! this year I discovered Arms of Andes leggings and they are my new favorite cold weather pant. I bought a couple, then went back and ordered more so now I think I have 7 pair. SO comfortable. SO warm but not at all hot or itchy. I wear them snow blowing with no other base layer and my legs do not get cold as they did in jeans or polyester. I love the color selection . so many other wool and alpaca vendors only offer a couple of neutral choices. i do wash these in the washer on the delicate cycle. i have put a couple in dryer for short periods of time because i found that i could size down after my first purchase so i was trying to shrink the larger size a little. they dry quickly -overnight on a drying rack. I am a huge fan and will continue to look at their new offerings next year!

So warm!

This is the second pair of leggings I have bought. They are so warm and comfortable. I love that they are 100% alpaca and don’t contain any synthetics. So happy I found this company, I am impressed with Arms of Andes.

Fit well, great for the bitter cold

I've been using these under regular pants as its gotten bitter cold; the fit is great. Feel sturdy and don't add much bulk. I don't find them soft; they are not irritating to my skin like regular wool, but there is a bit of scratchiness to them. I've used them over my silk long underwear, and that worked really well for staying warm and softer on the skin.. Happy with the purchase overall.

Love these leggings

This is my 2nd pair of the 300 Lightweight. They feel like a hug! They are not restrictive and oh, so soft, with only the occasional itch. They are not see through, are so comfy and keep me temperate, from the warmth of the indoors to the cold of the snow. I love natural fibers and love alpaca. Muchas gracias por un producto maravilloso!

Super cozy

These “lightweight” leggings are the warmest and thickest I’ve ever owned—don’t be led astray by the name! They’re soft with the slightest hint of itch, and I’m pretty sensitive and notice it but it’s not enough to bother me. They’re true to size and stretch nicely, I haven’t owned them long enough to know if they’ll get baggy. Definitely worth the price, 100% recommend if you run cool

It’s comfortable and warm. I have figure out how to bribg it back to it’s original shape.

love them

I purchases 3 of these leggings after realizing my polyester/nylon/acetate/acrylic clothing was the source of skin irritation, and I'm a new fangirl. I washed in washer and air dried. they stretch so may size down when I purchase them again, soon. I wear them daily here in my northern climate.

Hi Vicky! Thank you for the lovely review! We're so glad the leggings are working well for you and that you're enjoying them daily. Appreciate your support!

Nice leggings

I like the leggings. They were a little scratchy for the first few wears and unfortunately they do stretch out some. I can get 2-3 wears before washing if I’m not too active. I really wish they had pockets, but I don’t think the material would be able to support it. Temperature wise they were great in the 30s as leggings and comfortable into the 50’s. They are slim enough to work as a base layer for colder temps. I’m 5’4 145 with hips. The medium fits okay but does ride down. Overall I would buy again as a base layer but would likely choose something more elastic and with pockets for daily wear.

Hi Amanda! Thanks so much for your detailed feedback! We're glad you’re enjoying them as a base layer and appreciate your notes on fit and pockets. Your input helps us keep improving!

Scratchy Scratchy

This product is so scratchy I cannot wear it! Not sure what it is really made from but cannot be alpaca I’m sure.

Most comfortable leggings no pockets

These are the most comfortable leggings, but they have no pockets! If they had pockets, I’d buy more today.

My new favorite pants.

I’m not a big legging person but I love these leggings. They are super comfortable and breathable. They do not retain odors and air out wonderfully. I plan to get another pair in blue and black as well.

Sensitive Skin Approved

I have issues with a lot of textures when it comes to clothing. I have cut the tag out of every clothing item I have ever owned because feeling it would drive me insane. Needless to say I was hesitant to invest in a wool pair of leggings, but after trying to hike and workout in polyester I had to at least try it. And Thank God I Did!!!! They are incredible, no bad texture, no bad smells (unlike the plastic leggings) and the biggest one I hadn’t even considered no acne breakout on my butt and thighs after a hiking trip. Excellent investment!!!

Hi Rhianna,
Thank you so much for sharing your experience with us! We’re thrilled to hear that the leggings have worked out so well for you, especially given your sensitivity to textures and past hesitations. It’s wonderful to know that they not only feel comfortable but also make such a positive difference during your hikes and workouts. We truly appreciate your kind words and are so glad you found them to be a worthwhile investment!

Arms of Andes for the Win!

I have tried several variations of natural fiber (merino wool, alpaca) tights from different companies, and these are easily my favorite for the fit and feel! I tried them on and uttered an audible, “yes!!!” when they wrapped around my body like a tailored piece! I am shorter, and these tights are a perfect length! Many of the other ones I tried were too long. These are also so super soft and comfortable, no break-in necessary! Wearing them felt luxurious!! I rarely (read: never) write reviews, but I have done my research on this company and really appreciate what it brings to the world! So, this is also my way of expressing my gratitude! Mil gracias en serio! I am grateful to have a quality source for clothing! I will be purchasing another pair and spreading the word!! Keep up the great work!!!!:)

Hi J.A.
Wow! thank you for such a heartfelt and enthusiastic message! That’s exactly the kind of experience we hope to create!
We're especially glad they fit you perfectly and that the softness and comfort stood out right away. Knowing that you've tried different natural fiber options and found ours to be your favorite truly means a lot.
We’re also incredibly touched that you took the time to write a review, especially since you rarely do. Your support, kind words, and trust in our mission keep us inspired every day.
Mil gracias a ti, we truly appreciate you spreading the word.
