Super Undies 3-in-1 Waterproof Undies - A Diaper, Trainer and Swim Diaper in 1
€37,95 EUR
3-in-1 Diapers for Big Kids are a great option for people who need a diaper that runs above the size 7 stocked in grocery stores for teen incontinence. By itself it acts like a training pant, but add in a liner and you've got a waterproof cloth diaper for big kids! They sport a normal waistband, making sure no one knows what they are if they peak out. And of course, there is absorbency already built in.
Super Undies specializes in helping with potty training autistic children by providing the necessary feeling of wetness. These underwear get used for many reasons: delayed potty training, spina bifida, angel man's syndrome, Chiari malformation, neurogenic bladder, voiding dysfunction, and many others.
The 3-in-1 Diapers can be used as training pants (out of the box), a cloth diaper (with a liner), or as a swim diaper (as is).
- Features: Waterproof through the wet zone front and back, slim and trim appearance, 2 layers of built-in microfiber absorbency, internal pocket to add more absorbency
- Made in USA
- Fragrance and chemical free
- Include preference for Super Soaker Bombs or Super Soaker Liners in the order special instructions
- This item is being sold through Shopify Collective and is not available in store
Benefits
- Allows children to feel wetness
- Supports body awareness
- Helps strengthen the brain–bladder connection
- Encourages progress in delayed potty training, especially for autistic children or kids with sensory differences
