Extreme durability


Your items are designed with meticulous attention to detail at our Headquarters in Amsterdam, The Netherlands, using materials with the best water performance available and the highest quality components. 

Then they go through many design iterations with experts to make sure we find the optimal fit. 

Next, they are fiercely water tested on flexibility, warmth and protection, before the best artisanal ateliers manufacture them by hand. 

This way, you can be confident your items are ready for all the water fun that you'll throw at them for many years.



This bikini is constructed from the most sustainable fabrics we can find. The outside fabric and the lining are sourced in Italy and constructed from recycled materials. The yarn is produced from regenerated plastic bottles or recovered ocean plastics (like fishnets).

It is then made in a small family atelier in Portugal audited by us to ensure fair labour. In addition, we aim to minimise transport pollution by sourcing all materials close to the atelier.

And it's delivered to you in recyclable packaging.

We make your shipment carbon-neutral by funding innovative companies that pull carbon dioxide (CO2) out of the atmosphere and store it.

Go out on the water, be assured you take care of our planet and future generations.

Made to inspire confidence


Now why should you drop your style when hitting the water? Exactly, no reason whatsoever! 

We're on a mission to inspire confidence in your next surf adventure.

WALLIEN is recognised by many (fashion) media for the unique combination of superb style with great functionality and fit.

Great quality swimsuit, excellent design. I feel so comfortable and well covered. Moves well when getting active in the water. Great for sun protection in Australia. I recommend it highly.
