Hocosa wool undershirt for men in pure merino wool – in forest green

This is one of those things where you think: "oh, just an undershirt." Until you put it on. Then you feel the difference immediately. This woolen men's undershirt from Hocosa is made of 100% organic merino wool and you can feel it in everything — soft, breathable, and incredibly comfortable. No sweat, no cold, no sticky feeling. Just pure, natural temperature regulation, exactly what you need.

Why you want this undershirt

The wool in this shirt is GOTS-certified, which means it is produced entirely organically, animal-friendly, and environmentally friendly. So no mulesing, no chemicals, no microplastics. Just honest wool, straight from sheep that are treated with respect. And you can feel that — literally.

The color? A beautiful forest green melange that looks calm, but is just a bit more interesting than standard gray or black. And thanks to the low neckline and armholes, you can wear it invisibly under a shirt or sweater, without it pulling or pinching anywhere. It runs relatively small, so if you're in doubt, it's best to choose a size larger. This undershirt keeps its shape well, even after lots of wear.

The power of wool – why you will never want anything else

• Wool breathes – it keeps you warm when it's cold, and cool when it's warm.
• Self-cleaning – wool contains lanolin, a natural fat that breaks down dirt and odors. Simply airing it out is often enough.
• No sweat odor – wool neutralizes bacteria, keeping you fresh even after a long day.
• No microplastics – unlike synthetic fabrics, wool contributes to a cleaner environment.
• Gentle on the skin – merino wool has superfine fibers, making it itch-free and suitable even for sensitive skin.

Material & care

Made from 100% organic merino wool (GOTS). Wash only when strictly necessary, on a wool cycle with cold water. Use a mild wool detergent, such as Lanalicious, to keep the fibers supple and strong.

Availability

Also available as a short-sleeved shirt and long-sleeved shirt. Combine them as a layering system — perfect for outdoor work, hikes, or just for at home in the winter.

FAQ – frequently asked questions about the Hocosa woolen men's undershirt

Does the undershirt itch?

No. Merino wool has extremely fine fibers and actually feels soft. Even men who 'cannot stand wool' are often pleasantly surprised.

How often should I wash it?

Much less often than cotton! A quick airing out is usually enough; wool cleans itself thanks to the lanolin. Wash only when really necessary.

What makes GOTS-certified wool better?

GOTS guarantees that the entire chain is organic and fair: from the sheep to the seamstress. No mulesing, no pesticides, no exploitation.

Is this shirt suitable as a base layer?

Yes, ideal even. Thanks to the low neckline and armholes, you can wear it invisibly under shirts, sweaters, or dress shirts without it showing.

Doesn't it get too hot in wool?

On the contrary: wool regulates your temperature. You stay warm without sweating — that is exactly what makes wool so ingenious.
