ORTLIEB Office-Bag QL2.1 21 L

The Ortlieb Office-Bag QL2.1 21 L is built for daily commuters who need their belongings to arrive in perfect condition. Its IP67 waterproof rating means the bag can withstand temporary submersion up to 1 m for 30 minutes — far beyond what a typical rain shower will throw at it. The roll-closure seal (Rollverschluss) keeps moisture out reliably without any complicated fasteners. Mounting is effortless thanks to the Quick-Lock 2.1 fixing system, which is compatible with rack tubes from 8 to 16 mm in diameter. The adjustable rail can be fitted on either the left or right side of the rack, and swapping sides only requires reassembling the top rail. The bag clicks on and off in a single motion — gloves and all. Inside, the 30 × 40 × 17 cm main compartment holds two DIN A4 folders, pens, a phone and a laptop up to 15.4" when paired with the optional notebook insert. An integrated organiser, edge protection, support feet and a carry handle round out the practical details. The padded shoulder strap detaches cleanly for hands-free carrying once you reach the office. Made in Germany from PVC-coated polyester or PU-coated Cordura depending on the version, the Office-Bag weighs 1,550 g and features two large 3M Scotchlite reflectors plus a reflective Ortlieb logo for low-light visibility.
