With an absorption of 16 oz the regular day insert is designed for diapers with pockets. Our inserts are of type 'trifold', the micro-fiber always goes on top, it quickly absorbs liquids and the bamboo serves as a reservoir and ensures retention. Our inserts can be washed and machine dried but dry very quickly hanging. Do not use a softener in the dryer (in no stirring) as it will foul the insert and reduce its performance. For maximum absorption, it is suggested that you wash them 5-6 times before first use. For greater absorption, we suggest our night inserts (24 oz) available in regular and any bamboo.
