I'm looking for a relatively flatish camera case that would fit inside my ULA circuit backpack for those times when you want to keep it safer, inside the pack. So light is crucial, not too bulky, but big enough for a camera and a couple of lenses, batteries, etc. I know a lot of people bring nice cameras on the trail, but there are situations when you need to put them away.
I use one of these in jet gridstop for stuff...not necessarily camera gear.
You can pad it out with some cut up blue closed foam sleeping pad or similar to keep lens etc from rubbing and rattling.
The advantage of this is you can wear it as a day satchel or on the front of your pack or as a pack lid or a fanny pack. It is lightweight and water resistant
