Have the bag filled as the very first time with 1-2 expendable things and then capped and tested in the shower. So I'm amazed she's really, really waterproof! Since not too much was promised! Thus, even with expected heavy rains all the equipment stay dry: exactly what I was looking for, because I love to take pictures outside. Otherwise, the cushioning provides solid protection against all impacts normally in everyday life or if it falls suddenly out of hand. Much more I would not risk it. The small compartments can be used for practical things like note blocks, mobile phone, pens, keys, etc ... The strap is easily adjustable and the optical style I like, because it is very simple and unobtrusive. I am completely satisfied!
