Somewhere between the size of the average hip pack and a backpack, this Nike bag hits the sweet spot for your daily carry. Just enough pockets (two small mesh ones inside, plus the small one in front and the full-size one in back) to keep things organized. I was worried that the light color would stain easily, but after a few weeks of daily use, so far so good. The neon strap, however, does look like it's gonna need some regular spot cleaning. The reflective swoosh is a big plus for night shift.
