I personally use the Case Logic DCB-303. You can slide the G1X in sideways, with the filter adapter, filter, and 58mm cap attached. It is snug but there is very little room for extras. Two side pockets big enough for a battery, shutter release, SD cards, but not much else. NO room for the charger. Has a nice belt loop so you can wear it on your belt (if you don't mind the dorky look) or slide it on another bag strap or waist pack. Alternatively, it has loops and a shoulder strap, although these are pretty lightweight.
