Undiemeister® Light Green Casual T-shirt Crewneck Iceland Moss

A light green Regular Fit Casual T-shirt radiates all the freshness that you look for on warm days. Comfortable to wear directly on your skin, outdoors, in the warm sun. Or indoors, of course. And quality starts with the fabric, especially when it comes to casual T-shirts. That's when you need the premium feel you know from Undiemeister®. The combination of the fabric and the finish provide and optimal comfortable wearing comfort. We have chosen a slightly thicker, sturdier fabric for our regular fit casual T-shirt, with a higher percentage of organic cotton. Cool and fresh, with maximum ventilation and sturdy without being too heavy. That's exactly what you want on summer days, especially when combined with the well-known unique properties of Undiemeister®:

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

Iceland Moss™ offers soft freshness

Peering over the rugged landscape of Iceland, with its solid rocks, you will find oases of softness. Places where you might want to rest. In a soft, fresh green colour, almost pastel. A colour moss that contrasts beautifully with the dark rocks and stretches like a natural carpet. A colour you want to touch and feel. And that's exactly what you want when it comes to a T-shirt. Nature really does a good job, and we didn't have to think about this soft, fresh green colour for too long. A wonderful addition to our green colours Sea Breeze™, Highland Moss™ and Misty Forest™.    

Fabric made specially for outdoor comfort

A combination of two fibres to create a fabric that is ideal for casual T-shirts. In this case, a combination of organic cotton and Lyocell, made from Eucalyptus trees. Two natural components that make up the best fabric for regular fit casual T-shirts. A special composition, which creates a perfect stretch for casual T-shirts. Adding other components is therefore no longer necessary, less is more. The popular Mellowood® properties, sought-after and unique, can therefore also be found in our regular fit casual T-shirts.

With its maximum CO2-neutral production, Undiemeister® strives to achieve the optimum balance between premium wearing comfort and sustainability. Because this is the only way to create harmony between the highest possible quality and looking after the environment.

Design details with premium finish

“It's all in the details,” a the phrase suggests. And that's so true. You can recognise the premium finish by the details. They don't always have to be on the surface, but do make an important contribution to optimal comfort. This is also the case with the Undiemeister® regular fit casual T-shirt. The shoulder seam, for example, creates a more beautiful appearance, with more emphasis on the shoulders. The seam does not run flat on the shoulder, but rather 1 cm forward, improving the fit.  And the double stitching at the end of the sleeves has an invisible "flatlock stitch" on the inside.

The collar is finished in a wide sturdy rib, exactly 1.3 cm wide, without stitching, finished with a 1 cm wide, comfortable neck tape on the back, on the inside. Here too, no tickly label in the neck, but a print with only essential information. The washing instructions are therefore applied to the soft-woven label and attached to the inside of the underside of the shirt.

Another finishing detail is visible at the hem at the bottom of the shirt. It is finished with double stitching, also with a flatlock stitch on the inside. Placing these slightly higher creates a more luxurious appearance.

The coral stitching on the inside of the regular fit casual T-shirt, which is only visible on the inside, tells you that you are wearing an Undiemeister® T-shirt. The well-known Undiemeister® logo, against the orange background, has been subtly changed. So it is only visible to the wearer. But Undiemeister® have also designed a new logo, especially for the casual T-shirts. Subtle embroidery on the chest, measuring only 1.5 x 1.5 cm and tone sur tone. Chic, and practically the same colour as the fabric. This is the style you have come to know from Undiemeister®, never garish but decent, yet clearly recognisable. 

The regular fit is the logical choice, as this is the best fit for casual T-shirts. The T-shirt fits a little looser around your body, which feels comfortable and fresh in warmer weather. The neck is not too wide and not too tight, just right.

Finally, the length of the Undiemeister® regular fit casual T-shirt is also an important detail, because a short T-shirt does not come down to well over your trousers. A little bit more length, so you will no longer be showing a bare belly or back.

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.


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


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.


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.
