I have to preface by admitting that I'm not to keen on the man-purse, and just can't do the fanny pack.  Still, for my last vacation to Southeast Asia, I knew that my girlfriend would be having me tote some of her travel things, and I didn't want to be lugging loads around in my pants pockets.  Thus, I swallowed my (fashion) pride, and found this Pacsafe bag.  In choosing a bag, it came down to a small backpack or the small shoulder bag, but in terms of security, I thought that the Pacsafe was less likely to be pickpocketed than a backpack.  It was great for our trip, holding my two cell phones, camera, maps, receipts, sunglasses, and miscellaneous small knick-knacks.  Truth told, I still feel a twinge of gawkiness when I see photos of myself carrying it on our trips, but sometimes you have to put function over form, and the function on this bag is very good.
