Both compartments have zipper closure. The bottle holder is on one side of the backpack. There are 2 adjustable shoulder straps nicely padded for comfort when carrying the backpack. There are 2 zipper pulls for the large compartment, and 1 zipper pull for the smaller compartment. There is a nylon handle on top of the backpack, convenient for hanging the backpack on hook outside of classrooms, or any hanger. Bazic Products' logo is stitched in the front, on the bottom right of the small compartment for recognition.
