5 Reasons to Choose Merino Wool Clothing

Is Merino wool itchy? Is Merino wool warm?

Here are the top benefits of Merino wool.

1. Odor Resistance

Merino wool is naturally antibacterial.

What it means for you is that it doesn’t well. Well, of course, it will start smelling at some point, but it takes much longer to get to that point when compared to most other fabrics used in activewear and everyday clothing (most of activewear is made of synthetic fabrics).

2. It’s a Natural Material

Merino wool is a wool from merino sheep (New Zealand, Australia).

As a 100% natural material it’s also much safer than synthetics for most us. In fact, Merino wool allergy neutrality is one of the top reasons why people choose Merino wool clothing. You won’t get any allergic reactions while wearing a 100% Merino clothing. It’s important to remember that not all Merino clothing is made of Merino wool only, there are also a lot of blends on the market (some of them are worse, others – more superior technically). Make sure you know what you are getting.

Being 100% biodegradable, Merino wool is also safer for our planet.

3. Outstanding Moisture Management

Merino wool adjusts to you and the weather.

If it’s hot, it will keep you cool by transporting all the sweat and moisture away from your skin. If it’s cold, it will keep you warm. It’s all possible due to its fully natural moisture management system and moisture wicking features. Speaking of the cold weather, to stay warm it’s equally important to choose the right fabric weight — not all Merino wool base layers are good for winter.

For winter use look for fabric weight of at least 250 GSM.

4. Breathability

Great breathability is a must in a base layer clothing.

It’s what allows you to keep going long while staying comfortable. It’s one of the main factors that affect your comfort. And Merino is just great at that.

5. Ease of Use and Longevity

Not only Merino wool is durable, but also easy to take care of.

Merino wool is machine washable. But make sure to refer to the care instructions of the manufacturer of your shirt or pants, as they may differ. If you plan to wash your clothes while traveling, see our guide here.

And here we talk about showering while camping.

How to Choose a Merino Wool Base Layer?

How to find the best Merino wool base layer for yourself?

Let’s make this super simple.

Generally speaking it’s about these 4 simple things.

1. Fabric Weight

What are you going to use it for? In what weather?

Fabric weight is one of the main characteristic of Merino wool clothing. These 160 GSM, 200 GSM, 250 GSM (other times – g/m2), … to put it simply, they show how thin or thick is the fabric. The bigger the number, the warmer this base layer or these pants will be. If you want something for everything, look for midweight clothing, 200 – 230 GSM.

For cold weather and activities that include a lot of sitting or standing in one position – 250 GSM+. If you know you get cold easily, choose something like 400 GSM, and pack extra layers as well.

If you want the most lightweight base layer, look for 165 – 180 GSM.

2. Style and Fit

Are you planning to wear it on its own?

There are several kind of base layers. While some look great also when you wear them on their own, others are made to be worn under a mid-layer jacket. Some are more athletic fit, while others – casual. Choose what suits you the best!

3. Features

What kind of user are you?

Do you need this base layer for hiking and sports, or you plan to use it only for camping? Are you going to be moving around a lot, or will you be sitting or standing in one position a lot.

Remember also that not always 100% Merino wool will be the best option. In fact, for advanced users there are more superior fabrics, for example, a mix of Merino and polyamide and polyester. Because while Merino wool is a great natural material, it still has its own limitations, something that can be improved upon with the right manufacturing techniques, designs and blends.

Some merino tops feature thumb loops — a very useful feature in winter.

4. Your Budget

Decide upon your budget.

And choose the base layer that fits into it, and the one you like the most. There’s no reason to pay more for features you don’t need. Likewise, it’s not a good idea to get a cheap Merino wool base layer, if you plan to use it a lot — higher price often also means better quality and comfort.
