Although my 17 "laptop HP Pavilion (slightly larger than the measurements) just fits in the laptop compartment, but with a little caution goes the zipper to, nor separation for Dina4 has great papers. In the skin specialist is the accessory from the laptop, moment during the holiday the travel documents, a drink bottle and a light jacket accommodated. in a small half my Letherman, held a MP3 player.
