Simple in style, sophisticated in function. The Ortlieb Commuter Urban 21L Roll-Top backpack is made from robust Cordura material. This means it retains the casual look of a city backpack but is 100 % waterproof. The TPU back padding ensures a high level of comfort and ventilation, while a padded inner compartment provides storage space for your laptop. Your bike light can be easily attached to the loops on the outside. All in all, the Ortlieb Commuter is an ideal choice for anyone who appreciates a simple style with high functionality.
