In reply to Kemics:
As you have noticed, Mountaineering and lightweight backpacking gear is nowadays more in the less frills and no pockets trend.
but cheapo market ”hiking” sacks still tend to have such things as pockets. They might not be that robust though. Cheap.
the other direction is indeed that army/tactical stuff… with those molle system straps all around, you can pretty much accessorize as much as you want/need. Might end up lookin’ like a tool, can also be spendy.
the last option is photo/video gear. Again full of compartments etc. Tend to be spendy though.
perhaps a camera insert into a suitable bag is one option… only semi-spendy
