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.

Simply the best tshirts

The best tshirts ever. The feel of the fabric is very pleasant. I can also wear them for a really long time before I have to wash them and then they dry very quickly. So I wear them pretty much all the time. Nothing to complain about. Keep up the good work.

Ich trage kaum noch andere T-Shirts.

Die T-Shirts von Wolk sind fantastisch. Ich kann sie lange Zeit tragen, bevor ich sie waschen muss. Sie sehen nach all der Zeit immer noch wie neu aus, und meine ersten T-Shirts habe ich schon seit vier Jahren.


I have my T-shirts for 6 years, and they still look like new. I have all the colours, and they haven't faded one bit. I'm really amazed by the quality. Only my deo stains I had to treat with vinegar as described on the garment care page. It is a great tip to keep your T-shirts looking great.

Best tee ever

I also have t-shirts from other brands (even much more expensive), but I always get back to Wolk for the best ones. This is the third time I buy a copule of tees from Wolk... just because I like the new colors and because I needed bigger ones: the old ones, after being washed hundreds of times, are still perfect, like new.
These are virtually indestructible, the color never fades (even black remains as black as at the first wear), they are perfect in summer as well as in winter (Wolk sweaters are just as good and durable, btw) because of breathability and thermoregulation.
The fabric is super comfortable, the fit is nice and the colors are amazing.
They dry super fast when washed, maximum one night: if you only want to have two t-shirt for a lifetime, go with these.

Finally, the perfect merino t-shirt

I just wanted to say thank you so much for making such amazing t-shirts.

Ever since I found out about the benefits of merino I've been trying out quite a number of different brands. But each time something wasn't quite right, the fabric, the fit, etc.

I thought I had hit jackpot with Wool and Prince but for my 5 foot 10 slim build, the small was just a little too wide and "American" for me.

Your t-shirts have finally delivered, and the more European cut is just perfect. Thank you!
