Taking care of a DULO performance shirt or polo is veeery simple :)

Every DULO shirt is machine-washable. Make sure you set the temperature to warm (40 degrees Celsius or around 104 Fahrenheit), or below.

Once the washing is done, do not tumble dry. Just take the shirt out and hang to dry. Wear directly. Once you put it on, body heat will warm the fabric and straighten itself out (no ironing!). Your shirt will only look better as the day goes on ;)

Wash it, hang it, wear it.

What DULO owners are saying

I commute around the city on my bicycle. Since using DULO shirts, I arrive at my destination without looking or feeling sweaty. The shirts are really comfortable, fit perfectly, and I can wear them multiple times without needing to wash them. They look great too.

Erich, Amsterdam

It rarely happens that I get a clothing item in my hands that I can't stop touching :-) This shirt truly feels amazing and is a delight to wear. It even gets me compliments that I usually do not get for my white shirts. I actually look forward to time I wear this shirt. It's now in my wardrobe essentials!

Asbjørn, Amsterdam

Easy on you.
Easy on the planet.

The world's first 100% Biodegradable Performance Shirt

The highlights




100% Biodegradable fabric

Four-Way Stretch







Aquamove Technology

Aquamove technology enables the shirts to be sweat resistant and to dry quickly after washing.

"Wash it, hang it, wear it."


Silver Ions

The DULO Sustainable Performance line uses silver ions for antibacterial properties  — no more smells when sweating.

Easy Care

Machine Washable

No need for complicated treatment or trips to the dry cleaner. The shirts are machine washable to make it easy to care for and easy on your wallet.


Recycled Threads

Using a 100% recycled premium polyester core spun sewing thread consisting of entirely recycled plastic fibers, Coats EcoVerde has a significantly lower carbon footprint than virgin fibers.


Plastic-free packaging

Every shirt is shipped in a box made from 100% recycled paper, which is also 100% plastic-free. We use minimal dying for our packing, and only for the print.

Inside the box, there are no leaflets or books. All the information you need is printed right on the back of the lid and the whole box is held together by tiny magnets.

All DULO shirts are folded gently inside without any extra pins, paper or plastic around the collar.

Made in EU

The DULO shirts and polos are ethically manufactured in Bulgaria, using materials responsibly sourced in Europe.
