Office bag

The Ortlieb Office Bag QL3 is the latest incarnation of Ortlieb's waterproof briefcase pannier. What's changed from the QL2 bag is the attachment system: it's still quick-release but the hooks are recessed, so the briefcase looks more businesslike when you're off the bike. Or as Ortlieb put it: 'Flat mounting elements ensure smooth back side.' Yep.

The Cordo Tafelberg is a sturdy cycle-specific laptop bag that'll protect a laptop up to 15in either over your shoulder or mounted on your bike.

Made from incredibly tough fabric, it's clear that this is a bombproof bag right from the word go. It's no lightweight at over 1kg empty, but that's because it's got all the bells and whistles to protect your computer, including a whole lot of padding at the front, back and bottom.
