Fabric Care Guide
Thanks to alpaca wool’s naturally antibacterial and odor-resistant properties, you won’t need to wash your garment as often as synthetic clothing. In fact, most of the time, simply airing it out overnight is enough to freshen it up. Follow the guide below to care for your alpaca wool garment:
- Hand wash or machine wash on a gentle/wool cycle in cold water (50-68°F) using a mild wool-safe or pH-neutral detergent.
- Wash with similar colors.
- Do not bleach or use fabric softener.
- Do not tumble dry.
- Lay flat to dry and reshape while damp.
- Cool iron if needed.
- Store folded in a cool, dry and breathable space.
- Avoid hanging to prevent stretching.
- Try not to twist or wring the fabric too much.
Naturally Dyed Clothes
Although natural dyes are environmentally friendly, protective to skin and give pleasing colors, they do not bond with textile fiber materials like synthetic dyes. This may lead to slight color changes when sweating or rubbing and the colors may bleed a little.
We recommend using naturally colored clothing with other dark clothing or equipment like backpacks. We also recommend washing your clothing as little as possible, to ensure that the unique color lasts as long as possible.
Be cautious when using citric acid, as it may naturally bleach botanically dyed fabrics.

Frequently Asked Questions
About Alpaca
Why use alpaca wool?
While merino wool has long been the outdoor industry’s benchmark for high-performance natural fiber, alpaca wool has features that make it perfect for use in the outdoors. Research shows that alpaca wool is actually a higher performing natural fiber than merino wool, with improved comfort, moisture-wicking and temperature regulation properties. We also believe that alpaca wool is the most sustainable fiber available on the market, due to the way it is produced, sourced and turned into garments.
Where are Arms of Andes clothes made?
Arms of Andes technical outdoor apparel is made from start to finish in Peru.
Why does Arms of Andes make clothing in Peru?
As the world’s main exporter of alpaca fiber, Peru has the largest population of alpacas in the world and is the seat of knowledge about alpaca wool. Working in Peru allows us to ensure the traceability and quality of our products, as well as reduce our carbon footprint, particularly when considering shipping. Manufacturing the garments close to the source of the alpaca wool means that all transport during production is overland, so we only use air transport for distribution and shipping the final products to you.
Why aren’t other technical products made of alpaca wool?
Alpaca wool is expensive and historically thought of as a fiber for fashion, so alpaca clothing brands have generally focused on luxury and style instead of performance. At Arms of Andes, we have developed a unique fabric made entirely from 100% alpaca wool (the highest grade of alpaca fiber), which performs even better than merino wool in the outdoors.
How is alpaca wool different to merino wool, synthetics and other fabrics?
When compared to merino wool, synthetics and cotton, alpaca wool has been shown to be the softest, lightest, and most breathable option. It also regulates body temperature (in both the heat and the cold) and wicks sweat away from the skin even better than merino wool. Further, the structure of the individual fibers means that alpaca wool is softer and more comfortable than merino. You can find more information on our Alpaca Wool Performance page.
Is alpaca wool itchy?
Not for most people. Sheep’s wool has a reputation for being itchy as it contains a naturally occurring grease called lanolin, that can cause allergic reactions on human skin. Wool fibers also have microscopic “scales” on them which protrude from the surface and cause woolen fabrics to feel prickly or itchy. Alpacas produce tiny amounts of lanolin compared to sheep, reducing the probability of allergic reactions, and scales on alpaca wool fibers are smaller and protrude less, meaning that alpaca clothing feels much softer against the skin.
How to Use Alpaca Products
How do I know what size to choose?
The sizing of Arms of Andes products is based on the international sizing system and you can see the basis of these sizes in our Size Guide.
How do I care for my alpaca wool garments?
Alpaca wool doesn’t need washing as much as other fibers, as it is highly odor-resistant and has anti-bacterial properties. When Arms of Andes garments do need a wash, we recommend hand washing in cool water with a mild detergent and air-drying flat. Chemicals like fabric softeners and bleach are not needed and garments shouldn’t be dry-cleaned or tumble dried. You can see full care instructions here.
Is Alpaca wool just suitable for cold weather?
No! A key feature of alpaca wool is thermal regulation, which means it keeps you warm in cold weather and helps cool you down in the heat. Our fabrics are also highly breathable, and wick sweat away from the body, so you’ll be comfortable in our lighter base layers, even on hard hikes in hot weather.
What is the difference between 230 and 420 fabrics?
These numbers refer to the fabric weight system, indicating how much one square meter of alpaca wool fabric weighs. In functional terms, this means that the higher the number, the warmer the clothing will be. Garments with a 420 weight are the thickest and warmest and work well in cold conditions, while the 230 garments are lightweight and suitable for use in all but the warmest conditions. On the other hand, 110 garments are perfect anywhere: underneath other layers for added warmth on a cold hike or on their own in a hot yoga class.
What does layering mean?
Layering is a way of dressing to account for the varying conditions you will encounter during any outdoor activity. Layering starts with a thinner base layer, that sits next to your skin, followed by additional layers, of the same or increasing thickness. Using several thinner layers has been shown to be warmer than one thick layer, as a layer of warm air gets trapped between each piece of clothing, helping to keep you warm. Layering also means your clothing will feel less bulky, giving greater freedom of movement. It is important that the layers fit snugly – especially the one next to your skin – as this helps to maintain heat and improves the moisture-wicking capabilities of your layering system. Another benefit of layering is that you can adapt to changing conditions when you’re out and about, taking layers off as the day warms up and putting them on again when you feel cold.
