I picked up one of these bags https://www.amazon.co.uk/gp/product/B06XVSZ128/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
It’s quite nice for the money, probably not the best made bag in the world and highly unlikely to last you a lifetime but it’ll last a fair while and it is lightweight (one of my main pre-requisites) and fairly versatile and roomy. I added a CADEN padded camera insert that I had lying around and also a patch and some carabiners to taste. Not show in the picture below, it also has a large zip-up inside pocket at the back. I very much doubt if it’s water-proof but my National Geographic NG A2560 rain cover fits it very well.
I’ve also ordered one of their tactical MOLLE Phone Pouch Bag Gear Waist Belt Packs (catchy title) 🙂 https://www.amazon.co.uk/gp/product/B07Q2VJQGC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 to go one one end. This is detachable and will attach to a belt and serve as second pouch to hold extra stuff, a smallish lens, a mobile phone or maybe second camera like my TG-5 and spare batteries etc..
Small, shallow, vertical opening zip pocket on the left, I’ve put business cards in there. Double pocket, one with zip into which I’ve stored my rain cover and one larger pocket beneath it secured with buckle into which I’ve put my NEEWER 4 battery pouch. MOLLE loops and built in carabiner and a velcro loop patch.
Small side pocket with MOLLE loops.
Large back pocket probably best suited for flat items such travel paperwork, grey cards etc..
End with MOLLE loops to which I’m intending to attach the separate pouch that I ordered.
Inside with the CADEN camera insert fitted. The grey pouch on the end contains my small lightweight fold up rucksack.
NOTE the insert doesn’t come with the bag, I purchased this separately.
