Summit gear still make packs in Sydney and Katoomba, and they seem a bit cheaper than one planet… more classicly boxy, often zero zippers, ultra rugged. One planet looks superbly comfy though. Ezy, these listed packs are all tough as nails, and 20 years is not an unsually long time to be using them for. I still have my macpac torre from 1999 and there’s hardly a scratch on it, still carries 20kg+ comfortably, and I can happily push through scrub knowing nothing will catch and tear on it. I’d look away from the osprey packs and go for the Aus/NZ style of hardy canvas for this reason. I have a few you can try on, around that size you’re looking at. And Kristen has an old macpac that V could test too.
I know that might sound hard-nosed and anti-tech, but my sample of one osprey was not tough.
Like Pete’s experience, second had is great… Especially wilderness equipment and macpac, as i reckon their newer stuff isnt quite as great.
