It has pretty cool price and is comfortable for the back in summer. The sweat of my back and shoulder does not make me displeasure because of meshed shoulder string and mesh-cushion mixed back panel. It has also two compartments for notebook and paper. I uses it as commute-bag that contains 13 inch notebook, letter size some papers, 1 liter water bottle and miscellaneous articles.
I bought it one month ago. Its purchaing purpose is to prevent filled-out pocket of my pants that annoys comfortable walking in summer. It is good for ulternative container of palm-size book, keys and wallet. Unfortunately I have no iPad but its size and structure is sufficiently useable as another pocket.
