Thanks to very soft and smooth elastic around the waist and legs, your child can move freely in the water. Imse Vimse swim diapers consist of a layer of soft fabric that is leakproof in case of accidents and a stretchy bathing costume fabric on the outside. Snap fastenings make it easy to pull the diapers on and take them off, even when wet. Rinse the diapers thoroughly in chlorine-free water after use. Wash at 40°C (delicate wash programme) if necessary. These nappies are only for sale in the UK
