Flip one size organic diapers are made by the same makers of Bugenius and fall under the hybrid diaper category which means they can be used with either a cloth diaper insert or a disposable insert. This provides a lot of flexability and comfort for those parents that would rather not use cloth diapers while out and about. For best results use with Flip cloth inserts or Flip disposable inserts or the Flip Organic cloth inserts.
