The wool LIO comes with an organic cotton snap-in.
Lovey Bums wool LIO's have an outer shell that is essentially a wool cover with snaps for the snap-in diaper. There are two snaps at the top and one at the bottom for snapping in the diaper. The LIO shell can be used as a cover with other diapers as well.
The organic snap-in has two diaper layers of organic french terry fleece, and two layers of organic fleece in the doubler topped with organic velour.
