For the rest of the world, timelines vary a bit more. It can take 2 to 4 weeks to receive an order. Circumstances such as customs and speed of local couriers can extend this period.

Returns outside this timeframe may be accepted at the discretion of DULO and may only be refunded with store credit. Please note that we don't offer refunds for shipping fees, you will only be refunded the cost of the item(s) you return or the difference in case of exchanges with a lower-priced item(s).

Yes, of course. Just write to us at hello@weardulo.com and we will make the requested adjustments. There is a limited period until the end of the day in which you can request this change. Once your order has been shipped, we cannot make any more adjustments.

Just write an email to hello@weardulo.com and will arrange everything with you personally. Keep in mind, we do not offer refunds of the shipping fees, and you will be responsible for the shipping costs of the return.

We offer FREE shipping worldwide ;)

We ship from Bulgaria, the country of manufacture.


There's a lot our products offer. From the fabric, to the stitches, to the package, every DULO offers the best at the intersection of sustainability and performance.

Every DULO dress shirt and polo is made using the same materials:

- 100% Biodegradable Amni Soul performance fabric
- Premium Epic Coats Eco Verde threads from recycled polyester
- Natural Corozo Wood buttons
- 100% cotton for the interlining (the stuff inside the collar and cuffs)

Every DULO dress shirt or polo shirt comes rolled up in a neat little rectangular box that is 100% plastic free.

The box consists only of:

- Undyed recycled paper
- Two tiny magnet in the lid.

Inside the box there are no leaflets or other inserts. There's also no plastic used to hold the shirt together.

Every DULO dress shirt and polo is engineered to deliver the best performance, style and comfort that matches the demands of your active life. You'll have a guilt-free conscience, because all of this is achieved with a strong focus on sustainability so they don't become a burden on the planet at the end of their life. DULO shirts and polos are also extremely easy to care for, saving you a lot of time and money over time.

Every DULO dress shirt and polo shirt has the following properties:

- 100% biodegradable performance fabric
- Four-way stretch
- Wrinkle-resistance
- Non-iron
- Quick-drying and moisture-wicking through Aquamove technology
- Breathability
- Antibacterial and odor-repellent with the help of silver ions
- Machine-washable

Taking care of a DULO performance shirt 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.

Every DULO dress shirt and polo is made out of 100% biodergadable performance fabric called Amni Soul Eco®.

Compared to other fabrics, Amni Soul Eco® is eliminated from the planet in about 5 years. It's core feature is biodegradability.

In anaerobic landfills, its unique composition allows bacteria to gain access to and digest the waste materials, thus accelerating the biodegradation process

Like other biodegradable products, once it is in the landfill, Amni Soul Eco®, breaks down into organic matter (biomass) and biogas; both of these can then be exploited as new environmental resources as well as being used to cogenerate electricity.

No way! The biodegradation property is only activated once the fabric is in an anaerobic environment, such as a landfill. With normal day-to-day wear, the fabric is just as durable and long-lasting as any other performance fabric.
