What is Merino Wool? A Complete Guide to the World's Softest Natural Fibre
If you've ever stood in a shop holding a soft, surprisingly weightless wool blanket and thought why does this feel completely different from anything else I've touched? — there's a good chance you were holding something made from merino wool.
Most people have heard of it. Few people can actually explain what makes it different. And almost everyone considering a wool purchase eventually asks the same questions: what is merino wool, why is it so soft, and is it actually worth the price?
Here is everything worth knowing — clearly, honestly, and without the usual marketing fluff.
What is Merino Wool?
Merino wool is a type of natural wool that comes from the merino sheep, a breed originally raised in Spain and now found mostly in Australia, New Zealand, and South America. What sets it apart from regular wool is the thickness — or technically, the micron count — of each individual fibre.
Standard sheep wool has fibres around 30–40 microns thick. Merino wool typically falls between 17 and 26 microns. The difference sounds small on paper, but in your hands it is the difference between a scratchy school jumper and a blanket you actually want to wrap around your face.
The thinner the fibre, the softer the wool. Anything under 21 microns is considered "fine merino" and is soft enough to wear next to skin — even for people who normally find wool itchy.
Where Does Merino Wool Come From?
The merino sheep is one of the oldest domesticated wool breeds in the world. Genetic evidence suggests the breed has been around for over 800 years, with origins in the mountainous regions of Spain.
For centuries, exporting merino sheep from Spain was punishable by death — the wool was that valuable to the Spanish economy. Eventually the breed spread to other European countries, and from there to Australia and New Zealand, where the climate turned out to be perfect for raising them. Today, Australian merino wool sets the global standard for quality, with New Zealand and Patagonia close behind.
The wool is shorn from the sheep once a year, in spring. Shearing does not hurt the sheep — in fact, in domestic merinos, shearing is essential for the animal's health, since the breed has been raised for centuries to grow far more wool than they would naturally shed.
Why is Merino Wool So Soft?
This is the question almost every first-time buyer asks. The answer comes down to two things: fibre thickness and fibre structure.
Thickness: As mentioned above, merino fibres are dramatically thinner than regular wool. Thinner fibres bend more easily, which means they sit gently against your skin instead of poking it. This is why merino does not "itch" the way coarser wools do.
Structure: Wool fibres have a natural crimp — tiny zigzag waves running along their length. Merino has more crimp per inch than any other wool, which gives chunky merino wool its characteristic loft, springiness, and warmth. The crimps trap pockets of air, and air is what insulates you from the cold.
So when you hold a chunky merino wool blanket and it feels light but warm, soft but substantial — that's the crimp doing its job.
Is Merino Wool Itchy?
Short answer: no.
Long answer: it depends on how fine the merino is. Wool starts to feel itchy to most people at around 27 microns or higher. Anything below 22 microns is comfortable for nearly everyone, including people who say they "can't wear wool." The merino we use in our chunky merino wool blankets falls in the range of 24-26 microns so most people tolerate it well.
If you've had a bad experience with wool in the past, it was almost certainly with a coarser wool blend, not real merino. The two materials feel completely different.
Merino Wool vs Other Natural Fibres
People often ask how merino wool compares to cotton, alpaca, or cashmere. Each has strengths and weaknesses, so here is a fair comparison.
Merino vs cotton: Cotton is breathable but not warm. Merino is breathable AND warm — it actually regulates temperature, keeping you warm in winter and cool in summer because of how the fibres handle moisture. Cotton absorbs moisture and stays damp. Merino wicks it away.
Merino vs alpaca: Alpaca fibres are even thinner than merino and slightly softer to the touch. However, alpaca is less elastic and tends to drape rather than hold shape — it's lovely for shawls but less ideal for chunky knit blankets that need structure.
Merino vs cashmere: Cashmere is softer and lighter, but also more fragile and significantly more expensive. Merino offers about 80% of the softness of cashmere at a fraction of the price, and it lasts much longer with normal use.
Merino vs synthetic (acrylic): Acrylic is cheaper. That's its only real advantage. It does not breathe, does not regulate temperature, pills heavily after a few washes, and sheds microplastics into the water with every wash. Merino is the opposite on every count.
How to Care for Merino Wool
One of the biggest myths about wool is that it's hard to care for. It isn't — as long as you remember a few simple rules.
Don't put it in a hot wash. Hot water plus agitation causes wool to felt, which permanently shrinks the fibres. Cold water is your friend.
Wash on the wool cycle, or hand-wash. Most modern washing machines have a wool setting that uses a slow, gentle motion. Use a wool-specific detergent (or a mild one without enzymes).
Lay flat to dry. Hanging wet wool stretches it out of shape. Lay it on a towel to dry naturally.
Air it out instead of washing. Merino is naturally antibacterial and self-cleaning to a remarkable degree. Most of the time, you don't need to wash it — just hang it outside for a few hours and it freshens up on its own.
A well-cared-for merino blanket will last decades. Some pieces become heirlooms, passed down through families for generations
Why We Use Merino Wool
In our family workshop in Vilnius, Lithuania, we have worked with many different fibres over the years — and we keep coming back to natural merino wool for the same reasons our customers do.
It is soft enough for nurseries. Strong enough to last a lifetime. Beautiful enough to be the centrepiece of a living room. And every fibre comes from a real animal living a real life on a real farm — not a petrochemical factory.
We use it in our chunky knit merino wool blankets (arm-knitted by hand over several hours), in our chunky merino yarn for knitting and felting (for makers who want to knit their own), in our woven merino throws (lighter, perfect for spring and summer), and in our merino roving (raw fibre for spinners and felters).
If you are not sure which kind of merino product would suit your home, send us a message. Gintare answers personally and will help you choose something that genuinely fits your life — not just upsell you the most expensive option.
Sustainability and Ethics
Merino wool is one of the most sustainable fibres available. It is biodegradable — a wool blanket left in the ground will return to the soil in a few years. Compare that to a polyester blanket, which sheds microplastics for centuries.
Merino sheep are raised on natural grasslands, and well-managed wool farming actually helps maintain those ecosystems. The wool we source comes from farms that treat their animals well, with annual shearing for the animals' health and welfare.
If you care about the environmental footprint of what you bring into your home, merino is one of the easiest natural choices to feel good about.
Is Merino Wool Worth the Price?
Honest answer: yes, if you understand what you are paying for.
A handmade merino wool blanket costs more than a mass-produced acrylic throw because the materials, labour, and lifespan are completely different. The acrylic chunky blanket will pill within a year and end up in landfill within five. A good merino blanket will still be on your sofa in twenty years, soft as the day you bought it.
Per use, over time, merino wool is one of the most cost-effective purchases you can make for your home.
