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