Babyjem Liquid Proof Short thanks to the wide elastic band in Babyjem Liquid-proof protective shorts, it provides easy wearing and high waist protection. The double snap design in Babyjem Liquid-proof protective shorts allows your baby to move freely during sleep. With the towel part, the liquid is absorbed quickly and is confined to it for a certain period of time. Thanks to the waterproof membrane fabric, your baby’s mattress stays dry.
