I used this on my last trip to NYC and it was such a convenience. I'm a male, and after using this, I see why ladies carry purses. I did not want to have to be fumbling with my huge cell phone, wallet, etc. while on the subway and was a little freaked out about pickpockets, so I started scouring for solutions like fanny packs, and man-bags. This one had great reviews and coincidentally was available for my review so I pulled the trigger. The bag is very well made and feels solid. The seams are all very sturdy and the zippers don't feel cheap. As for space, I was able to carry my phone, wallet, extra cash, battery pack for gadgets, wires, and some nasal spray with room to spare. My one critique is that the strap could be made of a softer material so that it doesn't dig into your shoulder when you have the bag full. Other than that, this is a great value in my opinion.
