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.

To put it simply, it doesn’t smell. It’s resistant to odors.

For many it’s the number one reason to choose Merino wool activewear. Merino allows you to stay fresh longer.

2. It’s a Natural Material

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

As a natural material it’s also much safer than synthetics for most us. No itching. No allergic reactions. In fact, Merino wool allergy neutrality is one of the top reasons why people choose Merino clothing not only for sports, but also for everyday. Being 100% biodegradable, Merino wool is also better for the planet.

Make sure you choose 100% Merino wool clothing, though.

3. Outstanding Moisture Management

Merino wool adjusts to you and the environment you are in.

If the weather is hot, Merino keeps you cool. If it’s Arctic outside, it keeps you warm. It’s all possible due to its fully natural moisture management system and moisture wicking features. For the best performance, look for Merino blends. There are many that are technically better than clothing made of 100% Merino wool.

Speaking of the winter activities, it’s equally important to choose the right fabric weight. It’s especially true with Merino wool base layers and Merino wool base layer pants — not all of them will keep you warm on the coldest days.

4. Breathability

Merino wool is great with it.

5. Ease of Use and Longevity

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

Merino wool is machine washable. However, make sure to refer to the care instructions of the manufacturer of your shirt or pants, as they may differ. For the most lightweight Merino base layers and pants, hand wash is the safest choice.

How to Find the Best Merino Wool Underwear?

How to find the best Merino wool underwear for yourself?

Let’s make this super simple.

Generally speaking mostly it’s about these 3 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 these boxers or this base layer will be. If you want something for everything, look for 200. Something for cold weather? 250 GSM will be a good option. If you want the most lightweight Merino wool underwear – 150 – 180 GSM.

2. Style and Fit

Do you need it for everyday use?

Or do you plan to use this underwear for hiking and sports?

Choose the right style for your needs.

3. Your Budget

Decide upon your budget.

And choose the best boxers that fit into it.
