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.

The benefits

Why Alpaca wins

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.

Love them!

I tried the shorts on as soon as they arrived and they felt itchy but I decided to wash them and try again. They got a lot softer after washing. I wore them for three days on a trip in 80-90 degree heat and they were great. They stretch out a bit, but they weren't hot at all.

Finally something that fits and looks great!

Ordered one pair Alpaca bike shorts and received them quickly. These shorts are meant for extra comfort and warmth as underwear. Nice to know I can wear them as bike shorts too. Perfect fit! Luxurious feel. I love them. Immediately I ordered a second pair. If they came in all different colors I’d have one of each.

Faulty seams by design

Almost 2 months after I got these, the seams on both inner thighs along three points - are coming apart, so there's three little openings on both inner thighs. This is the 2nd pair that I've purchased that this has happened, so it definitely seems like a flaw in how they're stitched. Super disappointing for the price.

Two stars for comfort.

Comfortable

These are soft and comfortable, but after only 1 year the seams are already coming undone. I only wear them lounging around, and I wash them inside out on the delicate cycle using wool wash. I only wash them with other wool items. Disappointing. I'm hoping it's just a defective pair.

Womens Alpaca Biker Shorts

These shorts are very soft, yet hold their shape. The length is perfect for an active lifestyle.

No Plastic!

Fit like a glove----> and NO PLASTIC! Yay!

Womens bike shorts perfect in every way

These bike shorts are perfect in every way. At first when they arrived I was nervous that I would not like the way they felt because they don't have the wide waistband that I prefer, which would have been more like a yoga Style waistband. More narrow waistbands tend to dig into my waist. But these did not do that at all. They are soft, and the perfect length, and do not ride or roll up my legs. I bought this to manage thigh rub chafe when wearing a skirt, and for wearing in my raft guiding job as a base layer. I'll be buying more.
