Washable swim nappies: how do they work and why do you need them?

Washable swim nappies are specially designed for use in water: they keep poo in, let urine through and don't soak up water like an ordinary nappy. That keeps your little one light, mobile and comfortable, and keeps the pool water clean. In almost all swimming pools, swim nappies are compulsory for children who aren't yet potty trained.

What are washable swim nappies and how do they work?

Summer brings long days, warm sunshine and the perfect opportunity to cool off in the water. Whether you're enjoying a swimming pool, beach or lake, water fun is a favourite pastime for children and parents alike. For parents of young children who aren't yet potty trained, letting them enjoy the water safely and comfortably is a challenge. Washable swim nappies offer the solution.

They differ clearly from ordinary nappies in their construction and materials:

• Material: made from lightweight, quick-drying and breathable fabrics such as polyester or PUL (polyurethane laminate). The nappy doesn't get heavy and dries quickly, which is essential for comfort and freedom of movement in the water.
• Structure: a waterproof outer layer and a soft inner lining, often made of mesh or another absorbent material. Poo stays inside the nappy, while urine can pass through the fabric.
• Fit: elastic bands around the waist and legs give a snug but comfortable fit. That prevents leaks and gives your little one freedom of movement.
• Quality and style: if you're looking for high-quality washable swim nappies, Billie Wonder is an excellent choice. As well as being high quality, the swim nappies are also very stylish, available in a range of beautiful designs and colours. The attention to detail makes them not only practical but also a pleasure to use.

Why not use ordinary nappies in the water?

Ordinary washable nappies or disposable nappies aren't designed for use in water and cause problems there:

• Absorbency: ordinary nappies absorb liquid and hold on to it. In the water they soak themselves full and become heavy and uncomfortable for your little one.
• Limited mobility: a heavy nappy restricts your child's freedom of movement. That's not only uncomfortable, but can also be dangerous in the water.
• Skin irritation: prolonged contact with a wet, heavy nappy can cause skin irritation and nappy rash.
• Hygiene problems: ordinary nappies don't effectively contain poo in the water. That can lead to contamination of the pool and health risks for other swimmers.

Washable swim nappies offer a targeted solution to precisely these problems, with a special design that makes them suitable for the pool and the sea.

Why are swim nappies compulsory in swimming pools?

In almost all swimming pools, swim nappies are compulsory for children who aren't yet potty trained, and not without reason. Swim nappies keep poo in and let urine through; the chlorine in the pool water breaks that down quickly. That keeps the water clean and safe for all swimmers. So it's not just a matter of comfort, but also of hygiene and safety.

What does research say about their effectiveness?

Various studies show that washable swim nappies are effective at containing poo, the most important function of a swim nappy. A study by the Centers for Disease Control and Prevention (CDC) stresses that swim nappies aren't completely waterproof, but do contribute significantly to reducing faecal contamination in swimming pools.

Another study, by the National Environmental Health Association (NEHA), shows that swim nappies are designed to contain solids while letting liquids through. That's crucial: urine doesn't pose a major health risk in chlorinated water, whereas faeces can contain pathogens that cause illness.

What are the advantages of washable swim nappies?

• Reusable and sustainable: you use them time and time again. That saves money and is environmentally friendly: you reduce waste and protect the planet.
• Suitable for frequent swimming: perfect for families who regularly go to the pool or beach. Thanks to the durable materials, you can wash and reuse them often without wear.
• Fun designs: available in cute and cheerful prints, so your little one looks great in the water.
• No extra swimming trunks needed: a washable swim nappy doubles as swimwear. That makes changing easier and saves on luggage.
