T-shirts round neck from Undiemeister: the classic, made smarter and more durable

Sometimes simplicity is the greatest luxury. And that's exactly why a good round-neck T-shirt is so powerful. Timeless, minimalist and versatile, an indispensable basic for every modern man.

But at Undiemeister, a basic is never just a basic. Our round neck T-shirts combine the classic look with next level wearing comfort, technical fabric innovation and a fit you can rely on.

Why round-neck T-shirts are always good

Whether you need a layer under a shirt or are just looking for a T-shirt that always works: a round neck is the golden mean. Not too noticeable, not too deep, and always neat.

A good round-neck T-shirt offers:

  • A timeless design
  • A natural fit for any upper body
  • A look that works both casual and dressy
  • Technique and style in one, as you would expect

At Undiemeister, we perfect every detail, and you'll notice that from the very first wear.

Mellowood: soft power at the beginning

  • Lightweight fabric that breathes and performs
  • Durable fibers that can withstand dozens of washes
