The bag has been proven at a weekly trip through London super. It replaces a Lowepro Toploader 65 AW. Since I have a D7000 always Battery Grip use, the bag has to have a certain volume. Additionally, a second lens fits into (is not the case with the top loader). The bag is opened quickly through the clip locks, looks good, and does not fall too heavily on as a camera bag. The London rain did not manage even to the content. ;-)
