Engel Natur wool men's short-sleeve shirt – pure organic wool in slate

Do yourself a favor and treat yourself to some wool. This wool men's shirt by Engel Natur is one of those items that truly makes your life more comfortable. Made from 100% organic merino wool with the strictest certification available (IVN BEST), it is soft against your skin, breathable, odor-free, and entirely natural. The slate color is a timeless grey-anthracite melange — rugged, calm, and wearable with anything.

Why you will want this shirt

Wool isn't just warm. Wool works with your body. This hollow fiber adapts to your body temperature and regulates it, ensuring you are never too cold or too hot. Unlike synthetic shirts, wool breathes and does not retain odors. This shirt is therefore perfect as a base layer under a shirt, sweater, or jacket — or simply as a staple piece you'll want to wear every day.

Fit & styling

The shirt has a slim fit, allowing the wool to do its job optimally. Due to the natural elasticity of wool, it moves with your body. Engel Natur runs a bit longer than standard sizes, which keeps your back well covered — even when you bend over. The slate color features a subtly mottled structure that makes the shirt feel just a bit more luxurious than a standard basic.

Material & care

Made of 100% organic merino wool, untreated and free of microplastics. The wool is certified with the IVN BEST label — the highest achievable standard in organic wool. You hardly need to wash it: airing it out outside or hanging it in the bathroom is usually enough. The natural lanolin in the wool is antibacterial and keeps your clothing fresh.

Do you still want to wash it? Use cold water, the wool cycle, and a little bit of Lanalicious wool detergent. This keeps the fiber supple and nourishes the wool with lanolin — the same natural fat that protects wool against dirt and drying out.

Sustainable & fair

For generations, Engel Natur has worked from Southern Germany with one goal: to create clothing that is fair to people, animals, and the earth. The wool comes from KbT-certified sheep that graze on organic pastures, without mulesing or chemicals. Production is climate-neutral and completely free of harmful substances. Fair clothing with a clear conscience – just the way it should be.

What does KbT-certified mean?

KbT stands for “kontrolliert biologische Tierhaltung” – controlled organic animal husbandry. It is the strictest European quality mark for organic wool. Sheep are kept in an animal-friendly manner, without mulesing, antibiotics, or pesticides. The processing of the wool happens without chlorine or heavy metals. This preserves the natural strength of the wool – breathable, insulating, and durable.

Does this shirt itch?

No, this merino wool is exceptionally fine and soft. Even men who normally cannot tolerate wool wear Engel Natur without any problems.

How does this shirt fit?

The shirt fits true to size, with a slightly longer cut. Due to the natural elasticity of wool, it fits nicely without being tight.

Do I really not have to wash it?

That's right! Wool is self-cleaning. Hang it outside or in the bathroom while you shower and it will be fresh again. Only wash when absolutely necessary, using Lanalicious.

What is the difference between the colors slate and cinnamon?

Slate is a cooler grey-anthracite melange, while cinnamon is a warm brown shade. Both are limited editions, so they are only available temporarily.
