The Pros and Cons of All-in-One Cloth Diapers: A Complete Review for 2025

All-in-one (AIO) cloth diapers are a favorite among modern parents for their simplicity and ease of use. Unlike pocket diapers or prefolds, AIOs have absorbent layers sewn directly into the waterproof shell, so there's no stuffing or folding required. They work just like disposables—put them on, fasten, and go. But are they the best choice for every family? In this review, we break down the pros and cons of all-in-one cloth diapers to help you decide if AIOs are worth adding to your stash.

Whether you're a first-time cloth diapering parent or looking to expand your collection, understanding the strengths and weaknesses of AIO diapers is key. We'll cover absorbency, drying time, fit, cost, and more, and we'll highlight a few popular options from Squishy Lil' Campers, like the Mustard One Size Pocket and the Gone Fishing-XL Pocket, to give you real-world examples.

What Are All-in-One Cloth Diapers?

All-in-one cloth diapers are exactly what they sound like: a complete diaper system in one piece. The absorbent core—usually made of cotton, hemp, or bamboo—is permanently attached to a waterproof outer layer (often PUL or TPU). There are no inserts, no covers, and no folding required. Simply snap or hook-and-loop the diaper onto your baby like a disposable. This makes AIOs incredibly user-friendly, especially for caregivers, grandparents, or daycare providers who may be less familiar with cloth diapering.

Because the absorbent layers are sewn in, AIOs tend to be thicker than pocket diapers. This can make them more absorbent out of the box, but it also means they take longer to dry. Many parents love the convenience of AIOs for outings or quick changes, while others prefer the customizable absorbency of pocket diapers. At Squishy Lil' Campers, AIO options like the Mustard One Size Pocket offer a similar one-piece design with a pocket for added absorbency, giving you the best of both worlds.

• AIOs are the closest cloth diaper to a disposable in terms of ease of use.
• They are ideal for daycare, travel, or for parents with limited time.
• The sewn-in absorbency means no stuffing or folding required.

Pros of All-in-One Cloth Diapers

The biggest advantage of AIO diapers is convenience. You grab one diaper, put it on, and you're done. There's no need to pre-stuff pockets or fold prefolds. This makes AIOs a top choice for busy parents, especially during the newborn stage when diaper changes are frequent. They're also great for babysitters or relatives who might be intimidated by more complex cloth diapering systems.

Another pro is consistent absorbency. Because the absorbent layers are sewn in, you always get the same amount of padding. There's no risk of your baby shifting an insert or creating a gap that leads to leaks. Many AIOs also come with a stay-dry layer (like fleece or suedecloth) next to baby's skin, keeping them comfortable. For heavy wetters, you can often boost absorbency with a separate insert, but the built-in core handles most daytime needs. The Gone Fishing-XL Pocket is a great example of a diaper that combines the simplicity of an AIO with the option to add extra absorbency for overnight or heavy wetting.

• Extremely user-friendly—great for daycare and caregivers.
• Consistent absorbency with no shifting inserts.
• Often include a stay-dry layer to keep baby comfortable.

Cons of All-in-One Cloth Diapers

The most common drawback of AIO diapers is drying time. Because the absorbent layers are sewn in, they can take much longer to dry than pocket diapers or inserts. In a humid climate or without a dryer, AIOs may take 2–3 drying cycles or a full day on the line. This can be a hassle if you have a limited stash and need diapers ready quickly. Some parents solve this by buying more AIOs or using a faster-drying hybrid like the Mustard One Size Pocket.

Another con is that AIOs can be bulkier than other cloth diaper styles. The sewn-in layers add thickness, which might make it harder to fit smaller babies or trimmer clothing. They also tend to be more expensive per diaper than pockets or covers. Additionally, once the absorbent core wears out (after many washes), the entire diaper is compromised—you can't simply replace an insert. This can shorten the lifespan of AIOs compared to modular systems. Finally, some AIOs may not be as absorbent as a well-stuffed pocket diaper for heavy wetters, so you might need to add a booster.

• Long drying time—can take multiple cycles or a full day on the line.
• Bulky fit, especially on smaller babies.
• Higher upfront cost and shorter lifespan if the core wears out.

AIO vs. Pocket Diapers: Which Is Better?

When comparing AIO diapers to pocket diapers, the choice often comes down to convenience versus customization. Pocket diapers, like the Mustard One Size Pocket, have a hidden opening where you can stuff your own absorbent layers. This lets you adjust absorbency based on your baby's needs—more for heavy wetters, less for light ones. Pocket diapers also dry faster because you can separate the shell from the inserts. However, they require pre-stuffing, which adds an extra step to your routine.

AIO diapers win on simplicity: they're ready to go straight from the drawer. But if you value fast drying times and the ability to fine-tune absorbency, pockets may be a better fit. Many parents end up with a mix of both. For example, you might use AIOs for daytime changes and pocket diapers with extra inserts for overnight. The Gone Fishing-XL Pocket is a great overnight option because its larger size and pocket allow for maximum absorbency.

• AIOs: best for convenience, daycare, and on-the-go changes.
• Pockets: best for customization, faster drying, and heavy wetters.
• A mixed stash offers the benefits of both systems.
