I have tested several sizes of Manfrotto "Nano Styles Collection" and have to say that the bag I Nano suits the RX100. The camera does not wobble around in your pocket, but has enough space. The cushioning falls from relatively thin, as a second case with belt attachment BSP. but for hiking, etc. It is absolutely suitable. As a main pocket, I use the Sony LCJ-RXA, which has only one shoulder strap.
