is the size big enough for a small adult woman?
ROBERT F Yup, bought it for my wife. She is on the small side and wanted carry some baby stuff and purse contents in one bag.
Works well for her.
BRIDGETTE W No. It would fit a preschool aged child.
grace k My 4 year old uses it for preschool and when we travel. It has enough space for 2/3 change of clothes, lunch bag, and few of his toys.
Asia W absolutely not. i purchased this small backpack to use during shore excursions (while I was on a Caribbean cruise) but it wasn't large enough to fit an average size towel comfortably. In fact, this backpack would even be too small for my 6 year old nephew who is starting the 1st grade this year..
I hope this helps, and good luck to you.
