@N01R3 I spent a decade trying out different bags for everything including event work. Went through loads, more often by them not being quite right rather than wearing out. Settled on an Osprey one in 2018, it's lasted and I haven't wanted anything different since. They don't do the exact one any more, but do a few like it with detachable daypacks, which is a great feature: wear as one big rucksack, but can split into luggage/daypack, hold/cabin luggage etc.
