The best reusable swim nappy is one that fits securely around your child’s waist and legs, does not absorb pool water, is easy to remove after an accident and can be washed and used again.
For Australian families, it also helps to choose a nappy that works for regular swimming lessons, beach days and holidays without needing to replace it every few weeks as your child grows.
What should you look for in a reusable swim nappy?
1. A snug, adjustable fit
A swim nappy needs to sit securely around the waist and legs to help contain solids. Adjustable waist and rise settings make it easier to adapt the fit as your baby or toddler grows.
2. A design made for water
Everyday nappies absorb water and become heavy. A proper swim nappy allows liquid to pass through while helping contain solid bowel movements.
3. Easy removal
Side fastenings are especially useful when the nappy is wet or soiled. They allow you to open the nappy rather than pulling it down your child’s legs.
4. Washable, quick-care materials
Look for clear washing instructions and materials that can be rinsed, washed and dried between swimming sessions. Avoid fabric softener, which can affect performance.
5. A clean spare
Even if one nappy is enough for a short lesson, packing two gives you a clean backup if your child needs changing.
Sarah-Jane Collection reusable swim nappy sizes
| Size | Weight guide | Best starting point |
|---|---|---|
| Standard | Approximately 4.5–12 kg | Newborns and smaller babies or toddlers within the weight range |
| Large | Approximately 10–18 kg | Older babies and toddlers, particularly those close to 12 kg or needing more room |
The ranges overlap because weight is only one part of fit. Waist, thigh and rise measurements also matter. The nappy should be secure without digging into the skin.

Our practical recommendation
Choose the size that sits securely today rather than buying too large for future growth. Pack two nappies for lessons, check the fit before entering the water and change your child immediately after a bowel movement.
