Description
Big Kids · Ages 6–16 · Nighttime Diaper
Fitted Cloth Diaper with Snap-in Insert
A high-absorbency fitted cloth diaper and snap-in insert, sold together — designed for overnight bedwetting and nighttime incontinence in children ages 6–16.
Who this is for
Overnight protection that keeps your child comfortable through the night
Bedwetting at school age is common — and for many families, it goes on for years. This fitted diaper is built for that reality: it absorbs a full overnight void, stays soft against skin for hours, and pairs with the EcoAble Big Kids Pull-On Diaper to contain everything through the night.
The fitted design holds its shape during sleep and provides the high absorbency needed for longer nighttime stretches — giving your child a better chance of waking up dry and comfortable.
What's included
Everything in this set
The absorbent inner garment. Fits like a brief, absorbs like a diaper. Made from rayon and cotton layers with a snap closure at the front for a secure, adjustable fit. Not waterproof — worn under the pull-on shell.
Snaps inside the fitted diaper to boost absorbency. The rayon-from-bamboo facing stays soft against skin; concealed microfiber layers handle rapid absorption. Recommended for nighttime use.
How it works
Using your fitted diaper with the snap-in insert
Snap the insert inside the fitted diaper. The single snap keeps it centered and prevents shifting during sleep.
Your child puts on the fitted diaper. The front snap tabs allow you to adjust the fit securely at the waist.
Remove the pull-on shell, then the fitted diaper. Unsnap the insert and launder everything together in one wash cycle.
Key features
What makes this fitted diaper different
The fitted brief combined with the snap-in insert handles full overnight voids — significantly more capacity than a pull-on diaper with insert alone.
The contoured cut follows the body closely for a secure fit that stays in place through the night, with leg openings designed to seal well against the skin.
Snap tabs at the front allow you to fine-tune the fit and adjust as your child grows — useful across a wide range of body shapes within each size.
The inner facing is rayon from bamboo, which is soft, moisture-wicking, and gentle enough for extended overnight wear without irritation.
Materials
What it's made of
The outer layer of the fitted diaper combines rayon and cotton for flexibility, durability, and a soft texture that wears comfortably under a pull-on cover.
The inner layer against your child's skin is 100% rayon from bamboo — naturally soft, moisture-wicking, and gentle on sensitive skin during long overnight wear.
The skin-facing side of the insert is also 100% rayon, keeping the feel consistent across the entire garment.
Concealed microfiber layers provide rapid, high-volume absorption. Microfiber is always covered by the rayon layer and does not contact skin directly.
Sizing
Size by hip circumference, not age
| Size | Hip circumference | Rise length (front to back) | Estimated age |
|---|---|---|---|
| Junior 1 | 16–27 in | 17–20 in | 6–10 years |
| Junior 2 | 18–30 in | 19–22 in | 9–13 years |
| Junior 3 | 22–35 in | 21–24 in | 12–16 years |
If your child falls between sizes, size up for comfort and a better leak seal around the legs.
Big Kids Junior sizes (1/2/3) are separate from adult sizes and are not interchangeable with EcoAble adult products.
Honest assessment
What to expect
The fitted diaper with insert handles moderate to heavy wetting, including full overnight voids for most children. For very heavy wetters or children who go a long time between changes, some parents add an additional snap-in insert purchased separately.
The fitted diaper and insert absorb but do not contain. For overnight use, your child needs to wear the EcoAble Big Kids Pull-On Diaper (sold separately) on top. Without a waterproof cover, moisture will pass through to bedding and clothing.
The front snap tabs allow adjustment within each size, so the diaper can be fitted precisely to your child's body rather than relying on size alone. If your child is between sizes, size up for comfort and a better leg seal.
Care instructions
Washing your fitted diaper
Dispose of solids in the toilet, then store in a dry pail until wash day. Rinse cold or warm first, then run a full wash cycle with detergent. Avoid fabric softeners — they coat bamboo rayon and microfiber and reduce absorbency over time. The fitted diaper and insert can be washed together with other cloth diapers in the same load. Air drying the fitted brief helps extend the life of the material; the insert can be tumble dried on low.
FAQ
Common questions
-
Do I need to buy anything else for overnight protection?
Yes. The fitted diaper and insert handle absorbency but are not waterproof. For overnight use, you also need the EcoAble Big Kids Pull-On Diaper, which provides the waterproof outer layer. It is sold separately. Together, the fitted diaper, insert, and pull-on give your child complete overnight protection.
-
How do I know which size to order?
Size by hip circumference — measure around the widest part of your child's hips, below the tip of the hip bone. Junior 1 fits hips 16–27 in, Junior 2 fits 18–30 in, Junior 3 fits 22–35 in. Do not size by age or clothing size. If your child falls between two sizes, choose the larger size for comfort and a better leg seal. The front snap tabs allow some adjustment within each size.
-
Can I use the insert from this set with the EcoAble Pull-On Diaper as well?
Yes. The snap-in insert included with this set is the same insert sold separately for the Big Kids Pull-On Diaper. It is compatible with both products in the matching Junior size.
-
My child is a very heavy overnight wetter. Will this be enough?
The fitted diaper with one insert handles full overnight voids for most children. For very heavy wetters, you can add a second snap-in insert (sold separately) for extra capacity. The fitted brief's anatomical shape and adjustable fit also help prevent leaks at the legs — which is often where overnight leaks happen regardless of absorbency level.
-
Will my order packaging show what's inside?
No. All EcoAble orders ship in plain, unmarked packaging with no indication of the contents on the outside.
-
Is this product compatible with adult EcoAble products?
No. Big Kids Junior sizes (1/2/3) are a completely separate size system from EcoAble adult sizes (Small/Medium/Large). The fitted diaper, insert, and pull-on shells are not interchangeable between the Big Kids and adult product lines.
