Refunds - return your unwashed, clean items with our return slip, letting us know if you want store credit or a refund. A 10% restocking fee applies to refunds, which covers the subsidized shipping we paid on your behalf when shipping the original order (because nothing ships for just $3.95 anymore )
If you purchased multiple items and want to wash then before trying, wash 1 rather than all of them. This way you can still return the others if you are not satisfied.

Here’s how they work:
Use them as Training Pants (Out of the Box):
They come lightly padded with a waterproof outer shell, offering just enough absorbency for daytime accidents while giving your child the wet feeling needed for body-brain learning.
Use them as a Cloth Diaper (Add a Liner):
When you need full absorbency—just slide in a Super Soaker Liner. This will instantly transform them into a high-absorbency cloth diaper for longer outings or naps.
Use them as a Swim Diaper (As-Is):
No inserts? No problem. The built-in waterproof shell and snug fit make this the perfect swim diaper for pool days or water therapy. Meets standard swim diaper guidelines.
BONUS Diaper Cover (Over Prefolds or Fitteds or even Disposables):
If you need a bigger diaper than the size 7 found in grocery stores for teen incontinence, this is your answer!
