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.

Designed and made in one country

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.

Leggings

Thin material had a hole at the seam after one day's use. Customer service said nothing they would do, offer the standard 10% OFF next order. I should have ordered a heavier material. Would not recommend

Best Buy Ever

The Alpca long-johns that I purchased are super comfortable and warm. Highly recommend the purchase of this product!

Hi Henry,
Thank you for your recommendation! We're thrilled to hear that you’re enjoying the comfort and warmth of our alpaca long-johns. We appreciate your support and look forward to serving you again in the future!

Very happy.

Was very fortunate to win this along with matching long sleeve shirt. Very comfy and really helped in 25 to 35 degree nights (in a sleeping bag too) Got mine a size up because I prefer a slightly looser fit. Compared to regular long-johns with thicker material these beat them by thousands of miles. Will cherish these for as long as humanly possible.
Thank you :)

Hi Jeff!
How wonderful to hear you’re enjoying them! It sounds like they’re the perfect fit for those chilly nights. We’re so glad you won them and that they’re making such a difference. Thanks for sharing your experience, and here's to many cozy nights ahead!

Super comfortable

These are fantastic! They are very comfortable on the skin, no itching or anything like that. They keep my legs warm yet if you come inside, they don't cause your legs to overheat. They fit very well.

Hi Harold! Thank you so much for the wonderful feedback! We're thrilled to hear that you’re enjoying the comfort and warmth of the leggings. If you need anything else, don't hesitate to reach out!
