Recycled plastics & family atelier


This item is constructed from the most sustainable fabrics we can find: produced in Italy with yarn 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 factory.

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.

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.

Fits like a dream

Great quality suit, 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.

Fits perfectly with full movement

I was initially nervous about buying a wetsuit online without trying it on. I first dipped my toe in the wetsuit water with a WALLIEN Springsuit wetsuit and quickly realised a) that the sizing chart for Wallien is excellent as it fit so well and b) how incredible wetsuits were. I've had lots of lovely comments on the style.
