White men's undershirts from Undiemeister: the basics you don't see, but always feel

You don't see a good undershirt, but you feel the difference immediately. Our white men's undershirts are designed as a second skin: light, breathable, odour-reducing and completely invisible under your clothes. No visible seams, no creeping up sides, no creasing under your shirt. Just comfort, control and durability from early morning until late at night.

For men who know that undergarments are the foundation of style and confidence.

What is an undershirt, and why choose white?

An undershirt is a functional layer under your outerwear. It protects your shirt or sweater from sweat and odor, regulates temperature and prevents see-through. White undershirts are timeless and universally applicable, under white or light coloured shirts the most discreet choice.

Our white undershirts are:

  • Slightly fitted, without pinching
  • Made from the thin Mellowood fabric for added invisibility
  • Available in deep V-neck, V-neck or round neckline
  • With no visible inner tags or tactile seams

Everything you want to feel, nothing you want to see.

FAQ

Frequently Asked Questions

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

Do they stay white?

Yes. Mellowood is colourfast and resists yellowing wash after wash, provided you wash at 30°C and air dry.

Are they also suitable for perspiring men?

Absolutely. The fabric wicks away moisture quickly, stays dry to the touch and neutralizes odour - perfect for long workdays or hot days.

Can I also wear them outside as a regular shirt?

Technically, yes, but they are designed as functional undergarments. For casual T-shirts, we recommend our separate collection.

Should I wash it specially?

We recommend washing at 30°C, inside out. Air dry. The fabric stays in perfect shape even after dozens of washes.
