I'm a backpack guy (senior) and I never gave much thought one of these sling bags until a friend started looking at one. At that point I realized that when I didn't need to haul much, I can leave this bag on for the duration of my outing, unlike even a small backpack which is uncomfortable to wear when I'm sitting the bus. Furthermore, when I travel it has enough room for tickets, my 8" computer tablet and a snack. And because it's on my chest (even under my jacket if I don't have anything bulky in it) it's much more secure than other alternatives. This Taihexin bag is solid black, well-made and well-priced. I'm 5'9" 190 lbs and it rests flat on my chest even when I sit, although it may not work as well for someone with a small torso.
