Betty Lyn Swim Nappies

Swimming with Confidence only partners with high-quality brands.

Why We Partnered with Betty Lyn

Betty Lyn is a family-owned brand from Australia, started by a mom who also owns swim schools. When you own a swim school, accidents in the pool are simply not an option — so she designed a reusable swim nappy that actually works. And now we're bringing them to you.

The problem

Disposable swim diapers don't work.

They leak, they're bulky, and most pools require a reusable cover on top of them anyway — so why not skip the disposable altogether?

Saves you money — buy it once, use it all season
Works better — no leaks, no mid-swim disasters
More comfortable — your baby will thank you
Always there — no last-minute store runs before swim day

Our suggestion? Grab two. If there's an accident, change straight into the second and they're back in the water without missing a beat.

About Betty Lyn

Betty Lyn was founded by a swim school owner with over 15 years in the aquatic industry — someone who understands exactly what parents and swim schools need because she lives it every day. That experience shows in the details: a signature stitched bottom design, a soft wide waistband, and wide leg bands that create a secure yet comfortable fit — snug enough to help prevent leaks, gentle enough that babies and toddlers can move freely in the water. Reusable, durable, easy to clean, and made in modern prints kids love, these are the nappies swim schools trust in their own pools — and the ones parents keep coming back to.

What Families Say

"I bought two Betty Lyn swim nappies for my grandson in preparation for his baby swim lessons. We love the design, material, and thickness. The size guide chart was great for our 8 month old — I will definitely be buying additional swim nappies for my nieces and nephews!"
