A hybrid cloth diapering system is all about flexibility. With stay-dry, organic cotton & disposable inserts all fitting the same cover you are able to suit your diapers to your needs. This is a great option for people who would like to use a mix of reusable and disposable diapers. Inserts need changing at each diaper change while covers can be reused. You will need 4 or 5 covers plus 24 to 30 inserts (if choosing the cloth option).
