It is among the largest briefcases in our line. The main compartment offers space for a widescreen laptop/notebook computer and files. There are spaces for writing utensils, paper files, notebooks, a phone, the day to day stuff a person may need on the job. On each side of center there are huge pockets secured with twin leather straps. These aren't just pockets for papers, you can put big bulky stuff in there too like rain gear and a change of clothes.
