Outwardly, they look a lot like a schoolbag I had in the early nineties 😉
I’m sure these are well made and perfectly good if you’re after such a bag. Personally though, when I go into rugged terrain, I take my Lowepro Rover Pro 45L AW, which is half photo backpack – half trecking backpack, together with a holster type bag. This setup is much more practical I find than carrying a bag like the ones above (too annoying for serious hiking) + a normal backpack, or just a dedicated photography backpack (no room for trecking material).
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
