-
Soft & stretchy— Lovely and soft on the skin, with enough stretch to move freely. No scratchy fabrics, no tight edges.
-
Pool-proof— Chlorine- and salt-resistant — keeps its colour and fit after countless swims.

The difference
Donder swim, recognisable at a glance
Iconic Donder clouds and recognisable prints — not anonymous swimwear, but real Donder character at the water's edge.
-
Iconic Donder designs— Donder clouds with sunglasses, all-over print swimsuits or subtle Donder branding — recognisable from a distance.
-
Beautiful finish— Thoughtful details — a yellow-dot drawstring on the swim shorts, ruffle straps on the swimsuit, quality you can feel.
-
For boys and girls— Swim shorts and swimsuits — recognisable Donder style for the whole gang of kids.
Care
How to keep your Donder swim looking good for longer
A few simple things to keep your swimwear in top shape — no complicated fuss.
-
Rinse after swimming— A quick rinse in cold water after the sea or pool — protects against chlorine and salt.
-
Wash at 30°C— Wash at a low temperature in a laundry bag. No fabric softener — it affects the elasticity.
-
No tumble dryer— Hang in the shade — direct sunlight and the tumble dryer aren't kind to the fabric.
-
Colourfast— Stays bright and vibrant — even after a whole summer of heavy use.
-
Long lifespan— With the right care, the fabric stays soft and firm — and still fits next swimming season.
Frequently asked questions about Donder Swim
Our swimwear combines soft quick-dry fabric with iconic Donder designs — recognisable little clouds, beautifully finished, comfortable for swimming and splashing about.
Rinse briefly in cold water after every swim. Wash at 30°C in a laundry bag, no fabric softener. Hang to dry in the shade — no tumble dryer.
It differs slightly per product:
- Swimsuit Rainbow-Pink comes up a size large — order one size smaller than your usual size.
- Swim shorts Navy-Blue are true to size — choose your usual size.
Sizes are shown as a size group (e.g. 110/116), and the garment always fits the largest size in the group — so a 110/116 is actually a 116. Check the size chart at /pages/maten.
With normal use, the colour stays vibrant for a long time. For the best results: rinse briefly after swimming, don't leave it in direct sunlight for long, and don't put it in the tumble dryer.
Our Donder Swim is available in sizes 62/68 to 122/128 — from baby to kids. Check the available sizes per product.
At the moment our Swim collection is only available for kids.
Washed at 30°C and hung to dry, it keeps its shape and colour. High temperatures and the tumble dryer aren't good for swimwear fabric.
Our swimwear is made from a soft polyester-elastane blend, developed for use in water. Check the label of the specific product for the exact composition.
