Rayon Snap-in Inserts for Cloth Diapers — 3-Pack

Soft rayon-faced snap-in inserts compatible with EcoAble diaper covers and pull-ons across the baby, toddler, and Big Kids ranges. Use as the main insert, or as a booster for extra absorbency.

How you'll use it

One insert, two jobs

Depending on which EcoAble diaper you pair it with, this insert does one of two things. For some covers and shells, it's the insert — the absorbent layer that makes the system work. For the Big Kids Pull-On Diaper, it's a booster — a second insert that snaps in alongside the one already in the diaper for extra capacity without having to stack two full-thickness inserts.

Use case 1

As the main insert

For the EcoAble 3-in-1 Hybrid Cloth Diaper, snap it in to switch the hybrid from underwear mode into diaper mode
For the EcoAble Baby Heavy Duty Diaper Cover, lay it inside the cover as the absorbent layer
Rayon face against skin, microfiber core inside for absorbency

Use case 2

As an absorbency booster

For the EcoAble Big Kids Pull-On Cloth Diaper, which already ships with one insert, snap in a second one alongside for extra capacity
Slightly slimmer than the insert that ships standard with the Big Kids Pull-On — adds absorbency without doubling the bulk
Good for heavier wetters, longer school days, or travel

Compatibility

Which size fits which diaper

Match by diaper size, not age

The insert size is based on insert length, which is matched to a specific diaper shell or cover. Always pick the insert size that fits the diaper your child already wears or is about to buy. Size 1 inserts have been discontinued.

Insert size	Length	Fits this diaper	Use as
Size 2	13 × 5 in	EcoAble 3-in-1 Hybrid Cloth Diaper (Size 2)	Main insert
Size 2	13 × 5 in	EcoAble Baby Heavy Duty Diaper Cover (one size, 10–35 lbs)	Main insert
Size 2	13 × 5 in	EcoAble Big Kids Pull-On Cloth Diaper (Junior 1)	Absorbency booster
Size 3	16 × 5 in	EcoAble 3-in-1 Hybrid Cloth Diaper (Size 3)	Main insert
Size 3	16 × 5 in	EcoAble Big Kids Pull-On Cloth Diaper (Junior 2)	Absorbency booster
Size 3	16 × 5 in	EcoAble Big Kids Pull-On Cloth Diaper (Junior 3)	Absorbency booster

Not compatible with EcoAble adult incontinence products — those use a separate size system with dedicated inserts.

Who this is for

Four situations where a 3-pack makes sense

Hybrid diaper families

If your child uses the EcoAble 3-in-1 Hybrid, having extra inserts on rotation means you can switch between underwear mode and diaper mode without running out mid-week.

Cloth diaper cover users

If you've built your setup around the EcoAble Baby Heavy Duty Diaper Cover, these inserts slot in as the absorbent layer. Three at a time covers a full laundry rotation.

Big Kids heavy wetters

If your child has leaked through the standard insert in the Big Kids Pull-On Diaper, adding one of these as a second insert gives you more absorbency without stacking two full-thickness inserts.

Building a stash

Buying inserts in a 3-pack is the most cost-effective way to add to a cloth diapering rotation — whether you're just starting out or topping up an existing stash.

Key features

What makes this insert work

Cross-compatible across three product lines

One insert works with the Hybrid Diaper, the Baby Heavy Duty Cover, and the Big Kids Pull-On — useful for families using more than one EcoAble product.

Rayon face, microfiber core

The skin-facing layer is soft rayon from bamboo; the absorbent core is microfiber. Microfiber is always covered by the rayon and does not contact skin directly.

Snap-in for a secure fit

A single snap attaches the insert to the shell so it stays centered and does not shift or bunch during wear.

Sold in a 3-pack

Three inserts per order — enough to cover a laundry rotation for daily use, or to build up a spare supply for travel and back-to-back changes.

Materials

What it's made from

Outer / skin-facing layer

100% Rayon

Soft, breathable, and moisture-wicking against skin. Rayon is derived from plant cellulose and has a naturally smooth, cool feel.

Absorbent core

100% Microfiber

High-capacity absorbent fill. Pulls moisture away from the surface and holds it inside the insert. Always covered by the rayon layer — does not touch skin directly.

Dimensions: Size 2 is 13 × 5 inches. Size 3 is 16 × 5 inches.

Honest assessment

What to expect

Absorbency

One insert handles light to moderate wetting on its own — regular daytime output for most children in the compatible product ranges. For heavy overnight wetting or full voids, a single insert alone is not enough; pair it with a fitted diaper or use two inserts together in a compatible cover.

Booster framing is honest

When used as a booster in the Big Kids Pull-On Diaper, these inserts are slightly slimmer than the standard insert the pull-on ships with. You'll still feel the added layer — adding any second insert creates more bulk than a single insert — but less than you'd get by stacking two of the standard inserts.

Not a standalone product

The insert absorbs but does not contain. Without a waterproof cover, shell, or diaper worn over it, moisture will pass through to clothing. The insert and outer diaper work as a system.

Not for overnight on its own

For heavy overnight wetting or bedwetting, the better approach is the EcoAble Big Kids Nighttime Cloth Diaper Set, which pairs a fitted diaper with an insert for significantly higher overnight capacity than any insert-plus-cover setup.

Care instructions

Washing your inserts

Machine washable Cold or warm rinse first No fabric softeners Tumble dry low Air dry optional

Rinse cold or warm first, then run a full wash cycle with detergent. Skip fabric softeners — they coat the rayon and microfiber fibers and reduce absorbency over time. Inserts can be tumble dried on low heat or air dried, and can be washed in the same load as your diaper shells, covers, and other cloth diapering items. Absorbency improves gradually with regular laundering over the first several washes.

FAQ

Common questions

Which size do I need?

Match the insert size to the diaper you're using it with. Size 2 fits the EcoAble 3-in-1 Hybrid (Size 2), the EcoAble Baby Heavy Duty Diaper Cover (one size), and the EcoAble Big Kids Pull-On Diaper in Junior 1 as a booster. Size 3 fits the EcoAble 3-in-1 Hybrid (Size 3) and the Big Kids Pull-On in Junior 2 and Junior 3 as a booster. Check the compatibility table above for the full list.

Does the Big Kids Pull-On Diaper already come with an insert?

Yes. The Big Kids Pull-On Diaper ships with one insert included as standard. These rayon inserts are for families who want a second insert to use as an absorbency booster, or who want spares to keep the wash rotation going. You do not need these to use the pull-on as designed — they add capacity for heavier wetters or longer wear times.

Why use a booster instead of just doubling up the standard insert?

You can double up standard inserts, but stacking two full-thickness inserts creates noticeable bulk under clothing. These rayon inserts are slightly slimmer, so adding one as a booster gives you extra absorbency with less bulk than stacking two of the thicker inserts. For heavy overnight wetting, the better solution is the EcoAble Big Kids Nighttime Set, which uses a fitted diaper for higher capacity than any booster setup.

Can I use these with non-EcoAble diapers?

These inserts are designed specifically for EcoAble covers and shells with the matching snap layout. They may work inside other brands' pocket diapers as a lay-in insert — the rayon face and microfiber core function the same way — but the snap will only align with EcoAble shells.

Are these the same as the insert that comes in the Big Kids Pull-On?

Similar but not identical. Both have a rayon face and a microfiber core. These rayon inserts are slightly slimmer, which is why they work well as a booster layered alongside the standard insert in the pull-on diaper. For the EcoAble 3-in-1 Hybrid Diaper, the Size 2 and Size 3 inserts here are the same inserts that ship with the hybrid as standard.

Do I need to prep the inserts before first use?

One wash before first use is enough to get them ready. Run the inserts through a normal wash cycle, then dry as usual. Absorbency will continue to improve gradually with regular washing over the first several wash cycles.

How many should I have in rotation?

For daily use, most families find a total of 6–10 inserts across their full stash works well — enough to stay ahead of laundry without washing every day. A single 3-pack is a good starting top-up for families who already have a few inserts, or enough to cover occasional-use scenarios like travel or swim trips.

Will my order come in plain packaging?

Yes. All EcoAble orders ship in plain, unmarked packaging with no indication of the contents on the outside.
