Suitable from 5 to 15 kg (depends on the child's body size) The Pop-In nappy combines optimal absorbency with a trendy and colorful design in one size. The waist size of the diaper can be adjusted with the snap closure. The waist height is adjusted via press studs on the front, so a total of four sizes are possible. The large absorbent insert and booster are attached to the waterproof outer diaper with press studs. This keeps them in place. The diaper guarantees a good fit at any age thanks to the elastic edges and the double barrier. The inside is made of soft and absorbent viscose (bamboo). As a result, the diaper is not as bulky. The Pop-In insert set can be replaced with a new one if the pad is not completely wet. The inside of the outer diaper is lined with microfleece, including a mini absorbent core, which also moistens when the absorbent core is wet. That's why this diaper is more like an all-in-one diaper. So if a baby pees in the diaper several times over the course of three hours, the pad and outer liner will most likely need to be washed together. If you're looking for a system where you can use the cover over and over again, check out Pop-in's cover. You can equip them with all kinds of pads and assemble your diaper as you wish. Care instructions: Washable up to 60°C. The inserts are dryer safe, the outer nappy is not. It makes sense to separate the insert from the outer cover before washing. The weight of the wet insole can pull the elastics, especially during drying, and wear them out over time. Excessive heat can damage the PUL! Avoid drying the pul on the radiator or hanging it in direct sunlight during the hottest hours.
