I have now done nearly a year with my pack and can, with confidence, say it was worth every cent. Looking to buy another pack fro one of my kids so back on this site. Its been down south, up to the Pilbara and about to do another leg of the Bibblumun when the weather gets a little cooler.
You take a risk with anything second hand but there was only wear and tear, no zip/buckle failures, just mild abrasion marks.
