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.

Elegant longsleeves

I finally found my longsleeve merinowool T-shirts that don't look like a Ski baselayer. The fabric has a smooth texture and a certain shine that give them an elegant look. Wolk customer support is top notch! Thanks for the smooth service with the size exchange. I will be back!

Finally the long sleeves!

Wolk has become my favorite T-shirt over the past years. I am pleased that they come with long sleeves now. They will serve me well.
