With the Vario PS QL2.1 26L, Ortlieb creates a hybrid of a backpack and a bicycle bag. The bag has a volume of 26 liters and features the proven QL2.1 mounting mechanism on one side, allowing it to be securely attached to the bike rack. Once the destination is reached, the flexible front can be easily flipped over the hook rail, revealing shoulder straps on the now free side. This makes navigating the city comfortable. The "transformation" takes just a few moments and is intuitive. Optimally designed for urban use, the Vario PS includes a laptop compartment that can safely hold devices measuring up to 36 x 24.5 x 2.5 cm. A mesh outer pocket and a zippered pocket integrated into the reversible front complete the features. The roll closure allows for variable adjustment of the backpack volume to fit the contents. As is typical for Ortlieb, the Vario PS is, of course, waterproof.
