SIZE CHART IN PHOTOS

Soft, Comfortable & Sensory 3-in-1 Diaper for Big Kids and Older Children

You’ve done the research. You care deeply about finding the right solution for your child — not just any solution.

Maybe accidents started suddenly.

Maybe rashes never seem to clear.

Maybe disposable diapers feel scratchy, bulky, or age-inappropriate.

Or maybe you’re worried about how your child might feel — or be perceived — if someone notices they’re wearing a diaper.

If you’re wondering whether there’s something better, the answer is yes.

A Better Option for Delayed Potty Training & Older Kid Incontinence

Our 3-in-1 Waterproof Sensory Undies are designed specifically for older kids and big kids who need more than what standard diapers or pull-ups can offer.

They can be used as:

• Training pants for delayed potty training

• Daytime diapers for kids with incontinence or special needs

• A waterproof cloth diaper option for bigger kids

• A reusable swim diaper when worn without inserts

If you need a diaper larger than size 7 — especially for older children or teens — this may be the solution you’ve been searching for.

Designed with Sensory Learning in Mind

Unlike disposables that trap moisture and mask sensation, Super Undies are part of our sensory underwear system.

They are designed to:

• Allow children to feel wetness

• Support body awareness

• Help strengthen the brain–bladder connection

• Encourage progress in delayed potty training, especially for autistic children or kids with sensory differences

This sensory feedback is a key reason many families choose Super Undies over traditional big kid diapers.

Comfort, Dignity & Discretion for Big Kids

We know older children need products that look and feel age-appropriate.

Our 3-in-1 Waterproof Undies are:

• Soft and comfortable against sensitive skin

• Slim and trim, avoiding the bulky diaper look

• Designed to fit under regular clothing discreetly

NEW: A boxer/brief-style waistband adds even more discretion if the waistband peeks out.

3-in-1 Waterproof Undies Features

• Waterproof through the front and back wet zone

• Slim, trim appearance for dignity and confidence

• 2 layers of built-in microfiber absorbency

• Internal pocket to add additional absorbency as needed

• Made-to-order sizing for big kids and older children

Because they’re reusable, many families are surprised by how much money they save compared to disposables — especially over time. In fact, children can often stay in the same size for up to three years, making the long-term cost even lower.

One Product. Multiple Uses. Fewer Compromises.

Parents choose Super Undies because they don’t want to compromise between:

• comfort

• function

• dignity

• learning

Our 3-in-1 sensory undies are built to support real families dealing with delayed potty training, older kid incontinence, special needs, and swim use — all in one thoughtfully designed product.
