The SmallSprout™ One Size Insert is made of 3 layers of nice thick microfiber terry. Features a three sized-snapdown design allowing this insert to fit into a small, medium, or large setting of the One Size Diaper. This insert will fill up your pocket diaper on all sides to help prevent leaks, and provide a trim fit while still retaining a high level of absorbency.

NOTE: Each SmallSprout™ One Size diaper includes a One Size Insert
