The all-time-classic book pack for uni, office & travel. The Berkeley Rucksack from Jack Wolfskin is hard wearing, reliable & especially comfortable, it offers plenty of space but is still very compact. It is specially designed to carry books, documents & A4 files. There's tons of space for these in the two main compartments. & it will also carry your shopping or your gear for a weekend trip. & it's really comfortable, too, thanks to the Snuggle Up suspension system with its wide shoulder straps & even load distribution.
