i use this bag by maxpedition as my man-purse on my daily urban commute into manhattan.
the top pocket, that kind of puffed up top you see in the shot, is perfect just for my zune and triples with access right at the top. even if i bump into something, my gear gets no pressure since it is on the top of the bag, not on the side. the water bottle pocket is great - holds my Knirps umbrella and a regular sized poland spring water bottle at the same time. im never without an umbrella when it rains, and never thirsty.
also, i keep the UE metal case on this little pouch below that i attached to my pack above. sometimes i roll with the triples in there, depending on my excursion
