Made for

This merino T-shirt offers comfort at an unprecedented level. It feels soft against the skin, works thermo-regulating, breathes and is incredibly odour-resistant. You can wear it for longer without washing it. It is made in our CLIMAFORCE merino fabric for which we are so renowned. It is 30% stronger than traditional merino wool, making those quick holes a thing of the past.



  • Our acclaimed CLIMAFORCE merino is a blend of 80% merino wool and 20% Nylon. It is 30% stronger than 100% merino wool. We use only the highest quality superfine merino wool with a fibre thickness of 17 Microns.
  • It is the same fabric as our other T-shirts. The white colour is a bit transparent. It is perfect for an undershirt, but some people might find it too transparent for a regular T-shirt. 
  • The fabric weighs 170 gsm


  • Our merino wool is mulesing free and has the Responsible Wool Standard, RWS.


  • The fabric is knitted in Portugal
  • The T-shirt is made in Portugal

Superb quality!

After my great experience with the Alex Merino Shirt I quickly ordered two T-shirts. I am again blown away with the quality! It is really incomparable ! I have other merino T-shirts but the quality of the Wolk T-shirts are from a different level. The fabric is so smooth and it feels much stronger. I will be back for more!

My T-shirt for every moment, every day.

I have bought five T-shirts in the past two years. I am systematically replacing my wardrobe with Wolk's clothes. The two black Victor T-shirts I bought two years ago I wear almost daily under my shirts to work. They still look like new. At the weekend I wear the Oscar T-shirts. Once you have felt the quality of the Wolk T-shirts, you do not want anything else and even the often poor quality of other T-shirts bothers you. I am a fan!

This is not a T-shirt

I'm a shirt-man. I don't like T-shirts, they tend to deform very rapidly. But ... I got very curious about the description of the Oscar merino, and I liked it as the model showed it. So tried one, could always send it beack (great refund policy!)

And no regrets, this is finally a T-shirt that is no T-shirt. It sits very comfortably, falls around the skin instead of sticking to it. It barely wrinkles and the colours are deep. Great T-shirt.

The merino T-shirt that is built to last

Built with our own high-performing CLIMAFORCE merino wool  it offers all the comfort of merino wool but it is durable up to the last fiber.

It is wrinkle-resistant, odor-resistant and thermo-regulating ! And oh, did we mention that there is no need to iron it? Just dry it on a hanger and you’re good to go!

Once you’ve tried on this T-shirt, you’ll never want anything else again.
