I spend a lot of time on public transportation in my city...especially on trains. Riding a city train 8 hours a week means carrying enough to read, a snack for those times your train gets "stuck", glasses, and cash.  It can also mean spending at least half that time jammed uncomfortably up against some other commuter/train door.

This is the absolutely perfect bag.  I place my train pass in the front slot, my glasses in the pouch directly behind, my change goes in one of the side zip compartments. Inside is enough room for a medium size paperback and the interior pouch which attachs to the interior of the bag carries cash and one essential credit card (more space is available, but that is all I chose to carry.)

And, it is light!  Certainly not fashionista envy worthy, but more fashionable than a lot of other options and infinitely more useful.

Thank you, Baggallini!
