Maium Etymology

In Dutch there are hundreds of words and sentences to talk about rain, MAIUM is one of them. It is a word from the 'Bargoens', in which it can mean 'rain', 'water' or even 'canal' – of which we have quite a few in Amsterdam.


We are two friends from Amsterdam who grew up cycling through the rain and saw that traditional rainwear lacked both style and functionality. Inspired by years of wet bike rides, our aim is to design stylish raincoats that can adapt to unpredictable weather and busy lives. Designer Anita: “Regardless of whether we had a business meeting, visited a friend or went to a festival, there was always the risk of getting a wet suit every time we traveled from A to B. That's why we came up with MAIUM, on the road in style, knowing that you and your clothes are protected.”

Maium Word usage

‘Als ik MAIUM op m’n porem krijg dan gaan ik pleite’ – a saying that means, if the rain falls on my head I am leaving.


MAIUM is a product of its environment. With at least 130 rainy days a year and over a third of the land below sea level, we've gained a reputation for devising innovative ways to keep ourselves dry.



Hang a wet raincoat to dry, preferably on a hanger. Even a dry MAIUM raincoat will always have to hang on a hanger to keep its shape. Tell friends about your experiences with MAIUM. Expect and accept compliments.


Leaving a wet raincoat folded or crumpled in a dark place, such as in a bag. Iron your raincoat. Put your raincoat in the dryer. Forgetting your raincoat after Friday afternoon drinks or leaving it behind at a festival.

Washing instructions

All our jackets are washable at 30C without affecting the coating of the jacket.


All our front zippers are waterproof and open on both sides. If the zipper does get stuck, we recommend greasing it with a drop of silicone gel or spray.

Bike Poncho

Open the signature zippers on both sides. Throw the front panel over the steering wheel. Grab the handlebars through the special 'bicycle holes'. Or just let it hang over the knees.


Difference between Puffer and Lightweight Puffer

The Lightweight Puffer is made of Pongee fabric, which increases breathability, while the Puffer is made with a Polyurethane coating. The Lightweight Puffer is 6 inches longer than the Puffer. Both are filled with recycled plastic, not down.


All our materials are OEKO-TEX(R) Standard 100 certified. Our raincoats are made from recycled plastic. The OEKO-TEX(R) label guarantees that every component of the relevant garment, every thread, button and every other accessory has been tested for harmful substances and that the article is therefore harmless from an ecological point of view. The test was performed by independent OEKO-TEX(R) partner institutes based on the extensive OEKO-TEX® criteria.

Production Ethics

The fashion industry is one of the most environmentally damaging industries in the world, so it is vital that forward-thinking designers combine fashion and design to create sustainable, functional and timeless alternatives. A raincoat is, by definition, designed to protect us from the elements. The effort we make to reconnect with nature through sustainable design practices is our way of giving back and protecting the elements from us and our behavior. We want to prove that fashion and innovation don't have to spoil the planet.


All materials used are either made from recycled plastic or are completely biodegradable. In our jackets we use a variety of materials such as recycled PET, Organic Cotton, Pongee and PU.

Water resistance

All our raincoats are completely waterproof at water column 3,000 or 5,000.


All our pongee, lightweight and organic cotton jackets have a breathability rating of 5,000. All our PU coated jackets are not breathable. But by all means open the zips for fresh air!


No animal substances are used in the production of MAIUM raincoats, and all raw materials are not tested on animals.
