Smash Urban Tracker Backpack in Black, also Grey and black. Was $40 now $10 at Big W. Says 15 litres but it's probably closer to 30 litres capacity. I bought 3. Really nice overall design. At least 25 left at Runaway Bay gold coast QLD; 10+ Loganholme QLD. Probably nationwide…? PLUS Smash Duffle/ convertible backpack $10 as well.
