This item works as described to a T. It is my desk in a backpack that includes space for snacks and/or a lunch meal with drinks. It will hold all items needed for your daily commute to work and secure items such as a laptop/tablet, office supplies like post it notes, pens, high lighters, any documents printed out, ID badges, binders, files, etc. All of that plus extra space for your lunch and a few snacks/drinks. It has water bottle holders on sides and small net pouches with zippers inside of compartment areas for charging cables, vitamins/medicine, and sanitary items. I feel the makers of this backpack thought of pretty much everything you might take with you to get you through your work day.
