4-11kg mini OS

Mini OS covers with double leg gussets (4–11 kg) offer excellent leak protection and a snug fit for babies who have outgrown newborn covers but are still too small for standard OS sizes. The double gussets create two separate barriers around the legs, significantly reducing the risk of side leaks — especially useful for active babies.

 

Mini OS provides a trim fit without excess fabric, making the diaper comfortable and well-shaped. The soft, stretchy elastics adapt gently around the legs and waist without leaving marks. These covers work with a variety of inserts: prefolds, flats, light bamboo inserts, and small fitted diapers.

 

Because the cover itself does not absorb moisture, it can be reused multiple times as long as it stays dry inside. The breathable PUL material keeps the baby comfortable while offering reliable protection. This size is the perfect step between newborn and OS.
