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.

Alpacamazing!!

Simply the best pair of sweatpants I have ever worn!! This pair is actually the second pair I purchased. I liked the first pair (Maroon) I had to get a second pair. Incredibly soft, and so warm. The quality is off the charts! Very happy to have found a company making top notch sustainable products as well providing good jobs for the local community. Keep up the great work.

Best sweatpants I've ever owned, currently considering getting another pair.

They're incredibly soft, easily good to 20F weather walking around outside if you're not being actively rained on. If you are, they work as an excellent layer under something else, although you may have easier fit with leggings.

I love these

I will say I was a little hesitant in purchasing these. But after I received them, I found that they are the best “sweat” pants I have ever had. I do wish they had traditional pants as an option, but these are amazing.
Definitely get yourself some

Fit Better than I expected.

These sweatpants are very comfortable. I was worried the inseam would be too short for my height ;as I normally wear a 34/36 inseam, but was surprised these fit just fine and didn’t ride high over my ankles. These aren’t baggy sweats they fit to the body really well. It would be nice if they had a back pocket or leg pocket for my phone but overall I’m very pleased with them.

So comfortable!

These sweat pants are so comfortable and soft. Very warm, but not too warm. High quality. I have several pieces and love them all! Worth every penny. Really the only 100% alpaca option of this quality I have found on the market.
