The waterproof bike briefcase with roll closure can be mounted on the right or left side of the rack. It can be quickly mounted and easily taken off the rack single-handed. Two large 3M Scotchlite reflectors and a reflective ORTLIEB logo (except silver version of PD620 fabric) ensure safety in the dark and in bad weather conditions. Edge protectors and base feet on the rear and bottom ensure optimal protection of the bag. It features a padded shoulder strap for comfortable transport. The bag is available in two versions: with QL2.1 or QL3.1 mounting system.
