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.

Why Alpaca wins

Alpacas en los Andes peruanos

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.

Peru, start to finish

A family company

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.

Peru, start to finish

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.

Works perfect under jeans, turns any pants into thermals.

Title says it all, these were very comfortable for all day wear, and fit easily under jeans. They stay warm and dry, not scratchy at all.

Thank you for your feedback! We’re so glad to hear they work well under jeans and keep you warm and comfortable all day. We really appreciate you sharing your experience!

women’s sizes are

I ordered Men’s size because women’s sizes are UNREALISTIC, tiny waist cutting you in half all day. So soft and comfortable. I’m ready for winter!

Hi Mary, thank you for your review! We're so glad to hear you’re enjoying the softness and comfort of the leggings. Wishing you a warm and cozy winter!

Great layering leggings

My husband loves these leggings - warm, nice heavy quality, fit TTS according to AoA size chart.

Hi Lesli,
Thank you so much for sharing! We’re thrilled to hear your husband loves the leggings and that they fit perfectly. It’s wonderful to know the warmth and quality hit the mark too. We really appreciate your support!

Fits great, very comfortable

Fits like second skin. Not restrictive at in any way. Maybe just a touch itchy but it’s pretty much non existent unless you’re very sensitive.

Great quality product for a more sustainable future. Will recommend to anyone.

Hi Eugene,
We’re so happy to hear that! It sounds like the fit and comfort are just right, and we really appreciate your kind words about the quality and sustainability. Thank you for recommending us, it means a lot!

The ultimate "long johns"

I love my alpaca leggings. Historically I wore the 160 lightweight leggings but because I love them so much, I wore them all the time and wore them out. Lesson learned. Trying again but this time with the thicker (300 weight) leggings and maybe rotate through more than one pair!

Hi Korey,
Thank you so much for sharing your experience with our alpaca leggings!
It’s great to know you’re trying out the 300 weight this time around, and rotating through a few pairs sounds like a smart (and cozy!) plan. We hope the thicker version brings you just as much comfort and satisfaction.
We truly appreciate your continued support.
