How to Wash Merino Wool Shirt?

How to wash Merino wool t-shirt?

Unless otherwise mentioned, most of Merino wool shirts are machine washable, but there are a few things to take into account. Follow these simple steps, and your Merino clothing will last longer.

  • Turn your shirt inside out;
  • Use gentle cycle or wool wash/delicates option;
  • Use warm or cool water (up to 30 degrees);
  • Don’t use bleach or fabric softeners, to avoid risking on losing Merino’s natural moisture management features.

How to Choose a Merino Shirt?

How to find the best Merino wool t-shirt for your needs?

Let’s make this super simple.

Generally speaking, mostly it’s about these 4 simple things.

1. Style

This is up to your preference.

Choose what you like the best.

2. Density of the Fabric

When it comes to Merino wool clothing, there are only a few key characteristics.

One of the most important is the density of the fabric. The GSM number. Be it mens Merino wool clothing or women’s, it doesn’t matter, you see GSM everywhere. To put it simply, the higher this number the denser the fabric. So, if you are wondering is Merino wool warm or not, the answer is — it depends.

If the GSM is 200 or 220, yes, it’s gonna be a very warm shirt.

You shouldn’t expect the same warmth from an ultra-light 150GSM shirt.

3. 100% Merino Wool or Blend?

Feature-wise, high quality blends are significantly better than pure wool.

And when it comes to high performance, blends are often better than 100% Merino wool clothing. At the same time, it doesn’t mean than pure wool is bad. It isn’t. If you are an average person, going on short hikes once in a while, chances are that you’ll be totally fine with most of 100% Merino wool shirts for hiking. For top performance — choose a blend.
