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.

Beyond expectations

After many work shirts bought from Wolk, I decided to try their t-shirts to compare them to my merino t-shirts from two larger companies (one being a mountain range, and the other breaking the ice). Perfect fit, quality beyond my expectations, I barely want to wear the other ones. Next step is to try their polo shirts.

Best. Tee shirt. Period.

Not too thin. Not to thick. Silky soft merino wool. Wrinkle resistant. Odor resistant. What’s not to like?

Just wore this tee for 3 days non stop in Cordoba, Soain where the weather was hot and the sweat was real. 3 days! Didn’t wash it once. Just let it dry and presto! Ready for the next days.

Seriously great product. Well worth the $$$$ — and for a travel pro like me, it cuts down immensely on packing and laundry while I’m in the go.
