Black Long Sleeve T-shirt Volcano Ash, with the unique Undiemeister® properties

A long-sleeved T-shirt is also excellent for wearing as an undershirt, directly onto your skin. Just like the short-sleeved T-shirts and the boxer shorts, the fabric is the determining factor and the basis for the quality. Long sleeve T-shirts from Undiemeister®, of course made from revolutionary Mellowood® fabric, offer the following unique properties:

  • Silky soft
  • Pill-free
  • Antiperspirant
  • Maximum ventilation
  • Colourfast, even after washing
  • Hypo-allergenic and antibacterial
  • Minimal shrinkage
  • Thermoregulating

What exactly is Mellowood®?

Mellowood® offers an unparalleled combination of properties and is a new type of fabric developed by Undiemeister®. After years of research into natural fibres from beech wood, a special fabric has been created in combination with organic cotton that offers a perfect balance on all fronts: Mellowood®.

The balance in textile properties is completed by the maximum CO2 low production. A balance between premium quality and durability that benefits everyone. The Undiemeister® long sleeve T-shirts are the only ones to offer the unique and complete features of Mellowood®.

Black long sleeve T-shirts with premium finish: The most beautiful Long Sleeves

The white long-sleeved T-shirts also have the well-known high-quality Undiemeister® finish. The separately applied narrow collar (1 cm) has double stitching for extra strength. And no itchy label here either, because all information about the top is printed.

With the long-sleeved T-shirts, the shoulder seam does not run flat over the shoulder, but is placed 1 cm forward. This makes for a better fit and maximum comfort. It emphasises the shoulders. The ends of the sleeves are made with double stitching, whereby the "flatlock" is invisible and on the inside.

The hemming at the bottom of the top, also finished with double stitching and the flatlock on the inside, provides extra durability. A higher hemming creates a more luxurious look, something that looks fantastic on the long-sleeved T-shirts. The recognisable Undiemeister® logo against the orange background is subtly visible at the bottom left of the shirt, in a soft woven version.

Slim Fit is also what we have used for the long sleeve T-shirts. The perfect stretch of the soft Mellowood® offers a comfortable feeling under your shirt, jumper or pullover. Because Mellowood® follows the contours of the body exactly, and therefore fits like a second skin. Without a pinching feeling, without feeling that you are wearing the shirt. That depends on the sophisticated fabric thickness.

Like all T-shirts from Undiemeister®, the long-sleeved T-shirt also has extra length. This ensures that your shirt stays in your pants and that is so nice when it gets colder outside.

The Long Sleeves are finished with a round neck.

Undiemeister® black long sleeve T-shirt, black as ash from the volcano

With nature as the source of inspiration for our colours, we had the choice of countless black tones. Volcano Ash is chosen from the ash spewed by volcanoes during an eruption. Because volcanoes and eruptions differ, not every Volcano Ash colour is the same. We found beautiful black tones at the foot of a volcano in Iceland, and we immediately captured the colour.

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

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.
