Aolso Potty Training Pants – reusable 6-pack cotton training underwear (TPU waterproof) for girls

What these are for

Aolso potty training pants are reusable toddler training underwear designed to sit between nappies and regular children’s underwear. The idea is simple: they help your child feel “wet” enough to understand what’s happening, while giving you a bit of protection so you’re not constantly dealing with soaked floors. Over the day, they’re meant to support more confident toilet trips, not to replicate a nappy’s absorbency.

On paper, they’re built around a soft cotton outer shell plus a built-in waterproof TPU layer. That combination should make them comfortable to move around in, while the waterproof section aims to reduce the chance of leaks reaching clothing or carpets.

Key features that matter in day-to-day use

What stands out here is the training-focused fit and materials. These pants use an elasticated waist and elasticated legs to help hold the shape and reduce leakage around the tummy and thighs. For potty training, that matters because the “small gaps” problem is where most mess tends to happen.

The cotton outer shell is described as 100% cotton, with a soft touch intended for comfortable movement. Underneath, there’s a waterproof breathable TPU layer intended to hold enough urine to avoid the pants getting wet through. It’s a sensible setup for training days, but it’s not the same as diaper-level performance—so if your child is still having lots of accidents in one go, you may need to plan for quick changes.

Size choice and where it can go wrong

The pack notes two styles: 110 and 100. They’re described as suited to different age/weight ranges, so it’s worth checking the label guidance before you buy.

A practical way to approach it is to choose based on weight rather than age alone, because potty training pants that are too loose can leak more easily at the legs, while ones that are too tight can be uncomfortable. The listing suggests: - 110 style for babies over 15 months, suitable for 26–40 pounds - 100 style for babies 9–15 months, suitable for 18–26 pounds

If you’re between sizes, you may want to think about how your child fits existing underwear—this is one of those products where the “wrong” size can make the whole experience harder.

Reusable and washability

These training pants are described as machine washable and reusable for multiple uses. That’s a major part of the value proposition: you’re buying a set to rotate through washes rather than relying on disposables.

In everyday terms, that usually means you’ll want a simple routine: rinse or pre-wash where needed, then wash the batch, dry, and keep the spares ready for the next training session. The listing doesn’t spell out wash settings or drying instructions, so it’s sensible to follow the care guidance provided with the product to avoid wear on the waterproof layer.

Who they suit (and who should look elsewhere)

It makes sense if you’re actively transitioning from nappies to underwear and want a training option that’s soft and breathable on the outside, with a waterproof layer that helps with accidents.

It might not be a great match if your child needs something to fully replace nappies for heavy, long-lasting wetting, because the description positions these as not absorbing as much liquid as diapers. In other words, they’re training pants first, not a “maximum protection” solution.

You may also want to think twice if your child’s accidents are currently very frequent and heavy, in those periods, you could end up changing more often, even with a waterproof layer.

Practical micro-scenario: a typical training moment

Imagine you’ve decided to try a toilet routine after breakfast. Your child has a few “tells” but can’t quite make it every time. With these pants, the elastic waist and leg fit are designed to help keep the underwear in place, while the TPU waterproof layer aims to prevent the pants from soaking through. You still get the training benefit—your child may feel damp—yet it’s less likely you’ll be dealing with a fully wet change of clothes or a floor spill.

FAQs

How many are in the pack?

The product is sold as a 6-pack of reusable potty training pants.

Are they fully waterproof?

They include a built-in waterproof TPU layer intended to hold enough urine and reduce the chance of the pants getting wet through. That said, they’re not presented as a diaper replacement, so frequent or heavy accidents may still require changes.

Can I machine wash them?

Yes. They’re described as machine washable and reusable for multiple uses.

What size should I pick?

The listing points to two styles based on weight/age: 110 for 26–40 pounds (over 15 months) and 100 for 18–26 pounds (9–15 months). Choose according to the weight guidance.

Final verdict

Is it worth it?

A solid pick if you’re serious about toilet training and want reusable cotton training underwear with a waterproof TPU layer, elasticated waist and leg fit, and machine-wash convenience. For many parents, that combination is exactly what makes training pants feel workable day to day.

It may not be the best choice if you need maximum absorption like nappies, or if your child is still having heavy, long-lasting wetting where you can’t rely on quicker changes. If you do buy, the biggest practical thing to get right is sizing—misfit can quietly turn “training help” into “leak and change” every time.
