Undiemeister® Black Slim Fit T-shirt Round Neck Volcano Ash

The unique properties of the Undiemeister black T-shirt with round neck

The C-neck or round neck T-shirts by Undiemeister®, like our Undiemeister black T-shirt, are mainly worn as undershirts, directly on your skin. As with boxer shorts, the fabric is decisive for undershirts. The material is the basic principle when it comes to quality. The Undiemeister black round-neck T-shirt is made of the revolutionary Mellowood®  fabric offering the following unique properties:

• Silky soft
• No-pill 
• Antiperspirant
• Maximum ventilation
• Colourfast, even after washing
• Hypo-allergenic and antibacterial
• Minimal shrinkage 
• Temperature regulating

Black as volcano ash

Nature offers countless shades of black. The name Volcano Ash betrays the origin of the hue, the ash spewed by volcanoes during an eruption. Not every Volcano Ash colour is the same. There are differences between volcanoes and eruptions. The most beautiful black shades lie at the foot of a Volcano in Iceland and we immediately captured this colour

Premium Mellowood® textile with premium finish.

The Undiemeister® round neck slim fit t-shirts are made with a high-quality finish. The separately applied narrow collar (1 cm) is made with double stitching for extra support. No scratchy label on the neck either, all information about the shirt is printed on the fabric.

The shoulder seam does not run flat across the shoulder, but is positioned 1 cm forward. This offers extra comfort and a better fit. This is also called a “Muscular Shoulder Seam” because it emphasizes the shoulders a bit more. The end of the sleeves is finished with double stitching, this makes the “flat lock” invisible on the inside.

On the underside of the shirt you find the so-called “hemming”, which of course is also finished with double stitching, with the flatlock on the inside, for added durability. For an extra luxurious look, the hemming is applied a bit higher. The recognizable Undiemeister® logo against the orange background is subtly visible on the underside of the shirt, “soft woven” of course.

The sizing of the round neck t-shirt is Slim Fit. The soft Mellowood® fabric offers perfect stretch, for wearing comfortably under your dress shirt. Mellowood® follows the contours of your body exactly so that the shirt fits you like a second skin. And yet you don’t feel like you’re wearing the shirt, because of the ingenious thinness of the fabric. Because of the Round neck, the t-shirt is not easily visible under a dress shirt, even when you have the top buttons open.

All round neck t-shirts from Undiemeister® have a bit of extra length. This ensures that your t-shirt stays put in your pants.

The white shades of chalk cliffs.

The chalk white colour is not just white, but sought and found in nature. White is often cold and warm white is not really white. As is often the case, nature offers the answer during search for the most beautiful shades of white. The many facets you see in the white of chalk cliffs approach the amount of white tones you see in snow and ice. The chosen Chalk White is unmistakably white, and at the same time warm and tangible.

Unprecedented premium, maximum durability

Washing instructions

Washing your garments at 30 degrees is more than sufficient for Mellowood® fabric. Often, people think that washing at high temperatures is better for the end result. This is not the case because washing at higher temperatures can damage the product or affect the fibres. We have had our products tested using different washing methods and the best washing instructions have been explained below. Mellowood® is naturally a silky soft material, so the use of a fabric softener is not necessary. You can read the washing instructions for our products below.

Washing instructions Pullovers

The special Merino-Tencel combination requires a little extra attention so that the pullover retains its beautiful look and special properties. But rest assured, this is very easy. That way, your pullover doesn't always need to be washed. Because if you hang it out overnight, by the open window for example, it already smells nice and fresh again. If you still want to wash it, use the wool programme in your washing machine. Maximum 30 degrees, with the spin cycle no higher than 600 rpm. A (little) wool detergent is fine and always wash wool together with wool. No jeans or other clothes with zips with it. And to avoid wrinkles, flat drying is best.

Bleaching agents

Never use chlorine or bleach when washing our products. Chlorine and/or bleaching agents are very bad for textile fibres and can strongly influence the durability of the products. They are also very bad for the environment.

Ironing

The Mellowood® fabric is non-iron, so ironing is a thing of the past with Undiemeister undergarments.

Drying

We recommend not putting Undiemeister undergarments in the dryer after washing. The dryer can damage the product and shorten their lifespan. Line drying is sufficient and saves energy. Still want to use the dryer? Use a low temperature.

Shrinkage

The shrinkage of Undiemeister is equal to that of cotton undergarments. With the correct washing instructions (30 degrees), the fabric will hardly shrink. When in doubt, you can use a spin cycle of up to 600 rpm.

We are sure that when the washing instructions are complied with, our products will retain their quality and comfort. If a product no longer meets the requirements after washing, we would like to hear from you. We will then investigate this in order to implement any improvements. So if this happens to you, please contact our customer service and we will find a suitable solution.
