After lugging around a heavy backpack on my shoulder for the past few years, I finally found a stylish lightweight alternative with numerous pockets and compartments for the high-tech trendsetters out there with PDAs, cell phones, etc. The Sandbag can handle them all. It's not large enough to hold a letter-size paper or brief without getting a bit dog-eared but it holds books & mags great! I would give it a full 5 rating if it was just a titsy bit larger to hold letter-size letters and folders. But it's a great knock-around bag to/from work or to carry around on your leisure time (weekends) and it doesn't look like a pocketbook. Nice Oakley styling & highly-recommended.
