It's nice to have a wrap for baby and not have to pull over his/her head.  There are no neck tags to irritate baby's skin (the Disney label is printed onto fabric).

Fabric is a nice quality, thicker cotton.  Not so thick that it's uncomfortable, but sturdy and soft.  They tie on side (no snaps or velcro), which make it harder if you have arthritus in your fingers, but it's not tough if you're fingers are in good shape.  There are two ties, one on each side.

My baby is big and fills these out.  The sizing seems standard with other baby clothing brands.  Overall, very happy with them.
