3 compartment "flight" bag. I bought 2 as I planned to use one for work every day, just to carry the laptop and books, but never used the second. Main pocket has straps to hold a laptop in place plus a solid base which can expand the compartment depth to 12cm. Second compartment has a secure zipped section and another pocket with velcro for passport. Credit card and pen slots and a fob for securing keys. The third (front) zip compartment is for papers and smaller items. 2 clips secure the bag beyond the zips. A robust carry handle and a shoulder strap with anchor points front left and back right, which allows you to open the bag without everything falling out. Measurements are approx 50cm wide and 34cg tall
