If you've ever stuffed a wet swim nappy into a plastic bag at the condo pool, shoved it in your bag and then forgotten about it until Tuesday — this one's for you.
A wet bag is one of those things that once you have it, you wonder how you ever survived without it. It's simple, it's reusable, and it solves a problem every parent with a baby or toddler faces constantly.
Here's everything you need to know.
What is a wet bag?
A wet bag is a reusable, waterproof bag designed to hold wet or soiled items — dirty nappies, wet swimwear, muddy clothes, leaky snack containers — without letting moisture, smell or mess escape into the rest of your bag.
They're usually made from waterproof PUL fabric (polyurethane laminate), sealed with a zip, and come in various sizes from small (fits one swim nappy) to large (fits a full day's worth of cloth nappies).
Unlike a plastic bag, a wet bag is washable, reusable, and lasts for years. It's one of the simplest swaps a parent can make that's genuinely better for the environment and more practical at the same time.
Why Singapore parents especially need one
Singapore life means pool days, beach trips, water play at the park, and unexpected tropical downpours that drench everything in sight. Your child is wet more often here than almost anywhere else in the world.
Add to that the fact that most Singapore families are out and about all day — coffee at a café, lunch somewhere, a quick swim, then errands — and you need something that can handle wet items without contaminating everything else in your bag.
A plastic bag works once. A wet bag works forever.
What to use a wet bag for
Most parents start using wet bags for swim nappies and quickly realise they're useful for almost everything:
After pool sessions — pop the wet swim nappy and swimwear straight in, zip it up, and nothing in your bag gets damp.
At the playground — muddy shoes, wet socks, sandy clothes all go in without touching anything else.
Travelling — perfect for separating dirty laundry from clean clothes in your luggage. No more inside-out plastic bag situations.
Snack emergencies — some wet bags work brilliantly as insulated snack pouches for short trips.
Cloth nappy families — wet bags are essential. Keep a small one in your nappy bag for used nappies and a large one at home as a nappy pail liner.
What to look for in a wet bag
Waterproof lining — PUL fabric is the gold standard. It keeps moisture fully contained, doesn't absorb smells, and wipes clean easily.
Double zip — a secure zip means no accidental openings at the bottom of your bag. Some wet bags have two compartments — one wet, one dry — which is incredibly useful.
Size — for pool days with one child, a medium wet bag fits a swim nappy and swimwear comfortably. If you have multiple children or use cloth nappies, go larger.
Easy to wash — your wet bag should be machine washable. Hang to dry and it's ready for the next adventure.
Pretty enough to leave out — this sounds trivial but it matters. If your wet bag looks good hanging on your pram or sitting in your bag, you'll actually use it.
Wet bags and reusable swim nappies — the perfect pair
If you're already using a reusable swim nappy (and if you're not, read our guide to the best reusable swim nappies in Singapore), a wet bag completes the system.
After swimming: rinse the swim nappy, pop it in the wet bag, zip it up. Done. No smell, no mess, no plastic waste.
It's the kind of small change that makes sustainable parenting feel genuinely easy rather than like a chore.
Which Econaps wet bag size is right for you?
At SARVA we carry three sizes of the Econaps wet bag — all made from the same recycled rPET fabric as the swim nappy, all waterproof and odour-resistant.
The Mid Wet Bag ($18) is your everyday pool day companion — compact enough to slip into your nappy bag, big enough to hold a swim nappy and swimwear after a dip. This is the one most Singapore parents start with.
The Pod Wet Bag ($25) steps up for fuller days out — it holds up to 8 cloth nappies and is brilliant for families who need more capacity without the bulk.
The Big Wet Bag ($28) is the travel essential — use it for holidays to separate dirty from clean laundry, or at home as a nappy pail liner. Once you have one you'll find a use for it everywhere.
How to wash a wet bag
Machine wash on a gentle cycle with your regular laundry or with your cloth nappies. Avoid fabric softener — it coats the waterproof lining and reduces effectiveness over time. Hang to dry rather than tumble dry to preserve the PUL fabric.
With proper care, a good wet bag lasts 3–5 years easily.
