Ortlieb's Messenger Bag Pro is specifically built to handle the chaos encountered when riding 8-10 hours a day in big cities. It's made from Ortlieb's signature waterproof material to keep your payload from getting wet even in the worst weather. Two shoulder straps, a waist belt, and a chest strap keep the bag secure and a foam back pad adds comfort while improving ventilation. The roll-top closure allows for quick access and a flexible packing height. If you're racing the sun home large reflectors will increase visibility and once you get there you can stand your bag up in the corner thanks to the edge protectors and base feet. A large transparent window on the outside and an internal removable liner pocket and subdivider keeps everything organized when you're on the go.
