“Finally swimwear that actually makes sense”
You can tell this was designed by a mum. The coverage is amazing (no more constantly adjusting or worrying about sunburn), and the fabric feels so soft on my daughter’s skin. We use it for everything — beach, pool, even backyard water play. Obsessed.

“I will never go back to normal swimwear”
I honestly didn’t realise how stressful changing a wet swimsuit was until I used this. The snaps are a GAME CHANGER — no more wrestling my toddler at the beach or pool. The quality is beautiful and it still looks brand new after so many wears. Worth every cent.
— Emily R, VIC

“The only swimmers I pack now”
We live near the water and use these daily. They’ve lasted so well compared to other brands, and the bright colour makes it so easy to spot my little one. The snap change feature alone is worth it — especially during toilet training. I’ve already ordered more.

“Made beach days actually enjoyable again”
I used to dread swimsuit changes with my little one — it always ended in tears (for both of us 😅). This has completely changed that. The snaps make it so quick and easy, and the extra coverage gives me so much peace of mind in the sun. It’s honestly the most practical swimwear we own.

“You can feel the quality straight away”
As soon as I opened it, I could tell this wasn’t your average swimwear. The fabric is so soft and thick (in a good way), and the fit is beautiful. It washes so well and hasn’t faded at all. I love knowing it’s safe on my baby’s skin too — that was a big reason I bought.

Why “Forever Chemicals” Don’t Belong Near Our Kids
The Hidden Danger in Swimwear:
When we think about summer days — sandy toes, salty smiles, and bright kids swim moments — the last thing on our minds should be toxins. But many mainstream brands use what’s known as “forever chemicals” (PFAS) in their fabrics — and that’s where the story turns serious.
Forever chemicals are synthetic compounds added to make materials “water-resistant” or “stain-proof.” The problem? They never truly go away. These toxins linger in our environment and can build up in our bodies over time. Studies have linked PFAS exposure to hormonal imbalances, developmental issues, and immune disruption — outcomes no parent wants near their little one’s delicate skin.
At Len Swim, we believe that infant swimwear and newborn swimsuits should be as pure as their first dive into the ocean. Our pieces are made using Oeko-Tex® certified, toxin-free fabrics, ensuring your child is protected — not just from the sun, but from what’s hidden beneath the surface.
Because the memories you make at the beach should last forever — not the chemicals. 🌊
Shop our bright, sustainable kids’ swimwear — designed for comfort, confidence, and conscious parenting.
