The Basics

What is Alpaca Wool

This exuberant wool comes from the wool of Alpaca, a South American camelid identical to an Ilama. Alpacas are globally bred. This exquisite wool is known for its idiosyncratic molecular composition, combining the benefits of Merino wool and cashmere giving you a fine texture that is desirable for its softness, prompting excellent warmth, moisture-wicking breathability, and naturally hypoallergenic composition. Absolutely as fine as cashmere, this natural wool gives you ultra-luxurious feels and subtle texture that is hard to beat. 

What is Merino Wool

This top-notch wool comes from the wool of the Merino sheep, explicitly known for its soft touch and cozy comfort, indeed the most chosen fiber in the outdoorsy industry due to its well-documented attributes. 

The general benefits of Alpaca wool and Merino entail a few similarities that should be kept in mind while making the splurge. Both luxurious wools are merely the byproduct of natural protein fibers thus prompting a biodegradable utility. In addition these comforting yarns are rated as top of the line due to their breathability and thermo regulatory attributes i.e. keeping you cozy during the icy winters and cool during the scorching heat. And most importantly, they tend to be sweat wicking, naturally odor and UV resistant. However if you take a closer look you might find Alpaca acing the market.

A Comprehensive Break down to Alpaca’s and Merino’s Performance and Functionality

A vigilant analysis on the performance qualities of Merino Wool to those of the pure Alpaca yarns   that are exponentially composed of cent percent Alpaca fibers is imperative to tick all the quintessential facets to make a sound choice. 

Is Alpaca Wool better than the Merino Wool? 

Benefits of Alpaca Wool

Let’s break it down step by step to know how Alpaca holds upto Merino Wool.  

  • Softness
  • Have you touched the incredibly soft Alpacas? Alpaca fibers have a more uniform and smooth surface in comparison to the Merino, which makes them less itchy to the touch. These three factors are prudent to understand the imperative reasoning behind the plushy softness.  

  • Surface Scales on the Fiber
  • Under the microscope, the pictures illustrate there are tiny scales on the fiber that cause prickly feeling to the touch. But the detailed view defines that Merino fibers are more pronounced, protruding visibly from the surface than tha Alpacas; whose fibers depict scales that are relatively less protruding. This makes Alpaca wool more comfortable to the skin, whereas people find Merino fibers more itchy and irritating.

    Merino Fibers

    Alpaca Fibers

  • Lanolin 
  •  Lanolin, a wax that is found in the wool of Merino sheep, generally secreted by their skin’s pores to lubricate the wool and provide protection. However, this wax is not human friendly as it renders allergic reactions to people resulting in severe rashes and prickliness when comes into contact with the skin. Merino wool is processed via various chemical procedures to remove lanolin. Alpaca on the other hand secretes relatively less or none lanolin and is touted as the best hypoallergenic wool in the silhouette industry.

  • Fineness of the Fibers


    Fineness of the fiber is the measure of the diameter mainly counted in microns. The higher the microns, the thicker the fiber is. The Merino fiber is 19-21 microns in diameter, whereas the royal Alpaca yarns measure 18-18.5 microns. The explicit benefit of Alpaca wool is that it's fine fibers feel softer against your skin, tending to be ultra-light and commendably luxurious.  

    Warmth of Alpaca VS Merino 

    Does Alpaca wool keep you warm? 

    Alpaca fibers have a quirky structure composite of hollow voids throughout the fiber. These hollow voids function to trap air. These microscopic pockets facilitate their thermal attributes, prompting a warmer ambiance for the wearer. Furthermore, these semi-hollow structures make them extremely light weight in comparison to the Merino fibers of similar fiber size. Mainly bred in the chill climate of Andes Mountains, this Alpaca wool in winters are geared by nature to bear the freezing climates. 

    Tensile Strength

    The mighty Alpaca Wool is capacitated to be more enduring and resilient, that is they can bear more pressure and tension. Research indicates that Alpaca fiber has the tensile strength up to 50N/ktex, allowing it to craft apparels that can withstand intense wear and tear. Whereas, the Merino fiber can endure pressure up to 30-40 N/ktex.  


    It is the ability of the wool to wick away moisture from your skin as you perspire. Both wools are proficient in effectively absorbing the moisture and carry it to the exterior of your garment so that it gets evaporated. This fundamental attribute wards off odor and adds to the comfort of the wearer. 

    Water retention

    Alpaca Wool is famous for being extremely water resistant. It mostly holds 8% of their weight in moisture at most whereas the Merino fiber can lock 30% of it. This benefit of Alpaca dictates that it is a perfect insulator and dries quickly in comparison to Merino. 


    Yes, Alpaca is your eco-friendly companion. This superfine fiber is never processed under harsh chemical treatments and synthetic processes likewise in Merino where it undergoes “super wash” process to make it soft, washable and comfortable. This super wash Merino wool requires a blend with multiple other synthetic fibers like nylon to enhance its luxury but this adds to the micro plastic pollution in the environment.  

     Is Alpaca Wool Valuable?

     In ancient times, use of Alpaca wool was only reserved for the royal people. Its exponentially exquisite properties and vitality make it the goddess in the yarn industry. It will cost you a fortune to get your hands on the top-notch Alpaca but isn’t it worth it?  The Alpaca is double the price than the Merino wool because it is renowned for its durability and softness. 

    Benefits of Merino Wool  

      1. Merino wool in winters keeps you warm and cozy due to its closely laid fibers creating small air chambers that trap heat acting as an insulator and displaying climate regulation effects.  
      2. Merino wool in summers is capable of holding upto 33% of body moisture in its fibers, that is how you keep dry, thus giving you a cooling effect when the moisture evaporates. 
      3. It is odorless because its scaly fibers don't let bacteria embed on its surface. In addition it has a self-cleaning effect. The Merino fibers are composed of two types of cells that rub against each other which renders them effective at cleaning themselves.

    2. Merino Wool is not invincible. Despite being a temperature regulating fabric, its durability is questionable. Excessive usage results in holes over time.
    3. The merino doesn’t pop out of the ground like the popcorn in a microwave. The whole process requires time and patience.
    4. As the fibers are super fine you need to exhaust more raw material to curate an apparel.
    5. Though it is said to be an excellent moisture wicker, it does not release water as quickly as it is claimed.
