Long T-shirts from Undiemeister: smarter in fit, more comfortable in every detail

It sounds simple: a T-shirt, but longer. Yet you only notice the difference when you wear it. No more creeping undershirts, no T-shirt that's just too short after washing & no hassle when you move.

Undiemeister's long T-shirts are designed for men who know that details make all the difference. Made from the smart and silky Mellowood blend, they deliver not only extra length but more importantly extra:

  • Quality made from premium materials
  • Freshness all day comfort
  • Wearing pleasure silky soft on the skin

Why choose long T-shirts?

Long T-shirts are ideal for men who don't like undershirts that creep out of their pants, but instead prefer a subtly elongated silhouette. They provide extra coverage for undershirts under shirts or sweaters, adapt to your movement and give room for comfort. Perfect for those who travel a lot, work or simply look for a T-shirt that always fits well, without restricting.

Made of Mellowood: technology in a natural fiber

Most of our long T-shirts are made from the patented Mellowood:

  • 68% TENCEL™ Modal
  • 28% organic cotton
  • 4% elastane

This combination provides a silky feel, breathability, natural stretch without sagging and lasting colour fastness. The fabric dries quickly and is odour-inhibiting, keeping it feeling fresh every day, even with frequent use.

Comfort in every season, with every movement

  • Breathability allows air to circulate and prevents feeling stuffy
  • Moisture management quickly wicks away sweat, keeping you dry during exercise
  • Odour control prevents unpleasant odours thanks to the antibacterial properties of TENCEL™ Modal
  • Temperature regulation keeps you cool in the heat and comfortable in the cold

Whether you're exercising, relaxing or on the go: your body stays fresh and your head stays clear.

The perfect fit with extra length

Our long T-shirts are available in a slim fit for a slightly fitted and modern look, or in a regular fit for a little more freedom of movement. The shirts are available in sizes from S to XXXL, always with that extra length that does exactly what you expect.

What situations are long T-shirts ideal for?

Undiemeister's long T-shirts are designed for versatile use: under a shirt with no visible edge, during long days at the office or on the road, in outdoor activities or just as a modern solo shirt. They are airy, stylish and unobtrusively functional. Even in winter, they prove their worth as a comfortable carpet pad.

They are produced CO₂-neutrally in Europe and contain no microplastics or artificial odour blockers. Packaged in plastic-free, recyclable packaging, they also last a long time, good for you and the planet.

FAQ

Frequently Asked Questions

Man met wit T-shirt met ronde hals en groene boxershort zit op bed en trekt grijze lange sokken aan

How much longer are these shirts?

On average 4 to 6 cm longer than a standard T-shirt. Just enough to stay in your pants perfectly without looking too long.

Are they suitable as an underlayer?

Absolutely. They are perfect under a shirt or sweater, thanks to their smooth finish and breathable texture. But also strong enough to wear solo.

Do they shine through?

No. Thanks to the density of Mellowood and the right weave, the shirt remains subtle but not see-through - even after frequent washing.

Do they shrink after washing?

No. Durable pre-treatment keeps them in shape. Wash at 30°C and do not tumble dry for maximum longevity.
