I don't own a rucksack. Mainly because rucksacks bring back memories of school days, cheap holidays in hostels and sporty activities. Or those tiny little black rucksacks worn throughout the 90s. But rucksacks needn't be avoided.
This Cimarron Rucksack from Blondie Mania comes in black or chocolate leather. It's a decent enough size for a rucksack - big enough to carry your basics, but small enough so you don't end up yanking your shoulders back.
