Rounded fit that is not overly tight

Fit to baby's C-shaped body

It is natural that babies’ body shape is round

When a baby is first born, its body (back bone) is naturally curved like when it was in mother's womb. However it will gradually become straight during their development, especially when baby starts to walk.

It can wrap baby's body and fit perfectly to body's curve.

Tightening on the waist of toddler baby has been lessen! Gently wrap!

The world's first!*
The secret of the round shape is…
darts and stretchable sheets at the back and the crotch part!

By using highly stretchable material together with darts, diapers automatically becomes three-dimensional and round. This is the secret that they roundly fit babies' curled backs and their movements.
