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. 🌊

Newborn Swimwear for infants & kids/ infant beachwear

Finding the right swimwear for a newborn is about more than just choosing cute designs. A baby’s skin and developing bones require fabric that offers both movement, protection and comfort. Newborn swimsuits should do more than just look cute—they need to protect delicate skin. Our UPF 50+ fabric blocks harmful UV rays, ensuring your baby stays safe while enjoying the water. Our newborn swimsuits combine fashion with function, offering timeless designs in gender-neutral prints as well and vibrant block and floral tones.

Len is dedicated to creating newborn swimwear that meets these standards without compromising on style.
