The million-dollar question: what is merino wool and where did it come from?
Merino wool comes from a specific breed of sheep, yep you guessed it, Merino Sheep in Spain and since have been introduced in Australia and New Zealand. They’re quite tough breeds, thriving in scorching summers and freezing winters. Merino Sheep produces the finest and smoothest fibers of all wool making it more comfortable to the skin and less prone to holes.
Traditional wool is thick and coarse. Great for keeping us warm, but it is extremely itchy, bulky, and well…not stylish. By comparison, Merino wool is soft, smooth, light, and fashionable, all thanks to Australian farmers who’ve perfected the quality with selected breeding. Better than anything built in a lab, natural Merino Wool is the perfect performance fabric for the 21st Century that surpasses materials like cotton or synthetics. Merino wool marries style, comfort, and performance perfectly.
FAQS about Merino Wool
Is merino wool a good base layer?
Merino wool is my base layer for all my trips, it doesn’t matter if it’s warm as 35 degrees celsius or minus 20 and freezing cold. This base layer is naturally breathable, insulating and last but not least odour-resistant. What I also really like about merino wool is that it’s super soft and lightweight so it really feels like a next-to-skin layer. I know that some people avoid merino wool as base layer because the price tag, but did you know that merino wool is 8 times stronger than cotton. So in the end it’s better for your wallet to invest in the right gear at the beginning of your trip.
There are so much more reasons for me to go for merino wool and one of the facts you really have to know is that merino wool is naturally UV absorbing.
Merino Wool vs Cotton
Merino wool contains a chemical known as lanolin, this a natural wax found in sheep’s wool that repels rain and other moisture as cotton absorbs smells and moisture. Cotton is also more heavy than merino wool. To give you the best indication watch this short movie:
How to wash merino wool?
Merino wool can be washed in the washing machine, always make sure that you turn the item inside out and place it a meshing washing bag. Most of the washing machines have a special wool program and if not make sure to pick a cold water temperature(30 degrees celsius) and pick a low spin. You can use a mild soap, but make sure to avoid bleach and softener. As this is not good for the fibers of the merino wool.
You don’t have to wash merino wool after every wear cycle, my personal advice is to wash it after let’s say after about 5-15 wear cycles.
One thing I really want to mention about is that after your wash is finished you never hang your wet woolens. Instead you lay the items flat so the structure of the merino wool is in it’s natural shape. Another thing never put your merino wool on heather such as radiotor or direct sunlight as it can damage the wool structure. I know it really sounds difficult now to wash your merino wool, but believe me it’s not! I just wanted to make sure you treat your merino wool the right way, as you can enjoy it for years.
What does the weight or GSM mean in terms of merino wool?
I will never forget the first time when I was walking in the Decathlon to shop my first merino wool and I was really confused about all those numbers which were noticed on the merino clothing. So to make sure you don’t have the same as what I had, I will explain you what those numbers mean.
To inform you about the grams of merino wool per square meter most of the brands indicates a number like 500 and you will notice GSM or g/m2 on the clothing label tags. So this means the lower the number, the lighter the fabric. But I know in or minds we will always think that thicker is warmer than just a thin layer of merino wool, but really this is not true. That’s why I prefer to wear two lightweight wool layers instead of one thick base layer. But keep in my mind you really have to know how base layers work! Allright let’s dive into the numbers!
Lightweight (150-180 GSM): Most of the base layers are made of lightweight merino wool as mentioned between 150 and 180 GSM. During the summer I have a lightweight long sleeve t-shirt to protect my skin and to regulate my temperature.
Midweight (190-250 GSM): When you go around 200 it will be more like a mid layer or for winter temperatures I would recommend this as a base layer.
Heavyweight (260 – 320 GSM): I use this heavyweight merino wool during my breaks while hiking or on a cycling trip, so when I relax and don’t do any activity. As it is not that breathable anymore, I won’t recommend this weight during your activities.
Outerweight (330 GSM or up): This is used for the coats underneath your wind and water proof layer.
The Decathlon indicates the merino wool as follows: 100 beginners use, 500 more use, 900 intensive usage. You can also find information about the weight and the grams per m2 in the product information on their website.
10 benefits of merino wool
There’s a lot to love about Merino wool, so we’ve compiled a list of our 10 personal benefits that we’ve experienced with the material over time.
1. It helps to keep you cool in warm environments
If you think wool can only keep you warm, you’re wrong. It’s perfect to wear in warmer environments as well! In the warmer months, the wool fibers keep you cool and dry. A great benefit of merino wool is that it’s hygroscopic, which means it can absorb moisture, so sweat is drawn away from your skin where it can evaporate into the air outside the fabric. As the moisture evaporates, heat is released, cooling the air between your skin and fabric.
2. It helps to keep you warm in cool environments
Traditionally, wool is thought to be the perfect fiber for winter. The crimped composition of the fiber provides unbeatable insulations by condensing moisture and air inside the fiber, providing heat to your body. Merino wool is also a great material for the first layer when you want to stay warm with the layer-system.
3. It has an antibacterial effect which helps to keep odors away
Merino wool is unique in that it absorbs odor caused by bacteria—trapping their smell and keeping them from building up all thanks to the natural wax, lanolin. Merino wool is great for traveling or longer treks when you may not have as much room to pack, or the means to wash your clothes every day.
Wonderful news for all people dependent on deodorant: merino wool absorbs all odor molecules and only releases them upon washing. No matter how hot it is, you’ll feel fresh all day long. On top of that, you don’t need to wash it each time you’ve worn it. Just hang it in the open air and enjoy it again the next day.
4. It has anti-static properties
Since it’s one of the benefits of wool that it can absorb moisture, it tends to not create static electricity, which means it’s less likely to cling to our faces when we go to change our tops.
5. It’s wool, but it doesn’t itch
What is Merino wool better at than traditional wool? It’s super-fine and soft. A single Merino wool fiber is ⅓ the diameter of a human hair. It’s so fine, actually, that when it brushes up against the skin, it bends out of the way. It can’t be prickly like other wool fibers because it can’t stand up to the weight of itself. So it’s soft. Really soft.
6. It’s moisture regulating
Wool fibers are naturally hydrophilic, which means water-liking, they attract and absorb water molecules. Wool can absorb up to 30% of its weight in water and still feel dry to touch. When wool absorbs water molecules it pulls the moisture away from the skin to the surface of the fabric where it evaporates. Wool is able to release moisture into the air more efficiently than most fabrics.
7. It is easy to take care of
Already sold on Merino wool? It gets better. This fabric is quite easy to take care of since a huge benefit is that it is naturally antibacterial, which requires less washing than cotton or synthetics. On the road, this is crucial since it can be challenging to find a laundromat.
When you do wash Merino wool, you can just throw it in the washing machine on a delicate or wool cycle with color and fabrics. Another bonus for its easy-to-care-for scale- is drying is optional. Because of its elasticity properties, Merino wool retains its shape, which means you can throw it in your pack or carry-on and it comes out ready to wear.
8. It is sustainable
Merino wool disappears after about 12 months in the ground. That means that, when you’re done with your gear, the earth will take back this fibrous protein composed of amino acids—releasing carbon and nutrients back into the soil.
Synthetic fibers and cotton demand a great amount of manipulation and processing. Merino wool, however, is made of grass, water, and fresh air. The merino sheep that provide the wool graze the hills of New Zealand and Australia freely, delivering a new fleece harvest twice a year.
9. It provides UV protection
Depending on how they’re spun and dyed, Merino fibers help block out harmful rays from the sun (UPF 20+). Wool absorbs radiation throughout the entire UV spectrum. Cotton and synthetic materials only absorb at low wavelengths.
And since the sun typically does more damage in the mountains, it’s good to have all the help you can get.
10. It is easy to take with you
Merino is one of the best travel fabrics out there. Packing one Merino wool shirt is almost the equivalent of packing five cotton shirts when it comes to freshness. Because of its natural regulating properties, you can cut down on the variety of layers.
