6-15kg OS

( number of products: 28 )

OS covers with double leg gussets (6–15 kg) are our most leak-proof and versatile covers. The two separate elastics around the legs create a double barrier, giving excellent protection against side leaks — ideal for both daytime and nighttime use.

 

This size covers a wide weight range, fitting slim and chunky thighs equally well. The soft, stretchy elastics adapt to the child’s shape without leaving marks, while keeping the insert securely in place even during active movement.

 

These covers work with all types of inserts: prefolds, flats, bamboo inserts, long inserts, and fitted diapers. Since the cover itself does not absorb moisture, it can be reused several times as long as it stays dry inside.

 

Reliable, comfortable and adaptable — double-gusset OS covers are one of the most trusted reusable diapering systems for growing babies.
