At Undiemeister, comfort starts with the basics, and that means undershirts that not only fit perfectly, but are also responsibly produced. Our undershirts, available as a tank top, T-shirt or longsleeve, are made of the patented fabric Mellowood: a unique blend of TENCEL™ Modal, organic cotton and elastane. Fully CO₂ neutrally produced in Europe, with maximum attention to people and the environment.

Thanks to the slim fit The shirts fit closely to your body without pinching. And because they are extra long, they always stay neatly in your trousers, just as you would expect from well-designed undergarments. Whether you're moving, sitting or exercising, your comfort remains under control.

FAQ

Frequently Asked Questions

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

Is there a difference between casual T-shirts and undershirts?

Yes. Our casual T-shirts are slightly thicker, have a visible finish, and are meant to be an upper layer. But still: just as comfortable as your undergarments.

Are they visible under a shirt?

No. Thanks to the Desert Sand colour (for light skin types) and the deep V-neck, our undershirts are virtually invisible under white or light-coloured shirts.

Can you wear them all year?

Absolutely. Mellowood's thermo control makes them suitable for every season. Fresh in summer, comfortable in winter.

How often can I wash them?

Mellowood stays soft and in shape even after dozens of washes. Wash at 30°C, air dry for best results.
