This bag is perfect - perfect size, perfect storage.  Pocket for keys in front, slot for phone in back.  Inside is great too.  It's not "as nice" a bag as I usually have but I couldn't find anything that fit the bill and, honestly, whatever its flaws, it's the nicest bag to carry I have had in a while.  Just had it on vacation and it performed like a champ.  Big enough to hold a water bottle but not huge.
