If you’ve ever watched hordes of city workers streaming through the streets on a Monday morning, you’ll know that commuting can be tough. Your typical office bag just doesn’t cut it: after a while, it’ll fray at the seams or bust a zip. Even worse, on wet days it’ll leak water like a sieve, soaking all your stuff (including your carefully prepared board presentation). Not good. Ortlieb’s Office Bag is different: a tough, waterproof commuter bag with understated looks. Thanks to the QL2.1 or 3.1 mounting system, it attaches quickly and easily to the luggage rack of almost any bike.
