These OSFM Even Greener Fitteds are the perfect ‘any time’ nappy. Each OSFM fitted comes with one snake insert and one booster, both consisting of 4 layers of cotton fleece). This means 14 to 16 layers of absorbency in the wet zone! These nappies are thus ideal for longer trips out and about, nap times and even night times. For heavier wetters, simply add a padfolded flat or additional boosters between the fitted and the cover. The fold down rise makes these nappies especially long-lasting as they can be used from just a few months old right up to potty learning (5-18kg).
