Slim Fit T-shirts by Undiemeister: for the man who knows what fits

Some choices you make instinctively. You feel it right away: this is right. That is exactly the feeling our slim fit T-shirts evoke. They fit perfectly, accentuating your silhouette while offering unprecedented comfort. Made from our signature Mellowood fabric, these T-shirts are your stylish second skin.

What is a slim fit T-shirt?

A slim fit T-shirt is designed to subtly follow your body. Not tight, but slim fit. The sleeves fall elegantly around your upper arms, the waist is slightly fitted and the shoulder line follows your natural shape. The result? A clean look without excess fabric.

Our slim fit men's T-shirts are ideal for those who love a groomed look without compromising on comfort.
