Love this bag.  Perfect size for day trips.  I bought it for a cruise and it is perfect.  Plenty of room for necessities.  Some people said a notebook would not fit in -- I beg to differ.  A three-ring binder might not fit, but a spiral bound notebook fit in very comfortably along with camera, phone, keys, ID, wallet, sunscreen, sunglasses, hair accessories, cosmetics, etc.  And the cop holder on the side is a nice snug fit for a good sized bottle of water.  Very comfortable, easily adjusted -- great purchase.
