Pocket diaper, insert included. More photos below in the comments.

This diaper is sooooooooooo soft inside! Inside is minky, then hidden PUL, the outside is a football jersey type material. The name Jack and number 3 is embroidered on the back, and a star on the front. It's a medium, but the rise is a little shorter than other mediums we had (13"). The snaps are generous - this fit my son at about 4 months, as the snaps can overlap for a smaller waist.
