I bought the bag for vacations and similar occasions where I do not always want to lug a big bag / backpack. Accordingly, this little bag just served its purpose. It more does not fit a DSLR + lens clean. Inside a mesh pocket for spare battery / memory card. Outside also two small mesh pockets, which I know so far, however, what to do, because they are too small for accessories. I get here my EOS 100D incl. 18-55mm kit lens into it, and do so even just having mounted lens hood. The shoulder pad of the strap slipping me constantly while running, but is not bad because you actually do not need in this lightweight combination. Rights is the camera in your pocket, in my opinion quite good, it makes a very stable and shock-resistant impression.
