The Blueberry One Size Combination Inserts are a unique combination of microfiber terry and organic cotton/hemp that provides you with the only insert you will ever need for your child's diapering years. Two layers of microfiber terry quickly absorbs the wetness while four layers of organic cotton/hemp fleece in the wet zone keeps the wetness in. Three snap settings allow you to adjust the size of the insert from small to large. When trifolded and snapped, it creates 6 layers of absorbency where the baby needs it most. Includes three inserts.
