ORTLIEB Seat-Pack QR is a waterproof saddlebag designed for bikepacking, touring and demanding bike adventures on singletrack, mountain passes and gravel routes. The patented Seat-Lock mounting system provides a stable connection, while the abrasion-resistant PU-coated nylon fabric offers durability for off-road use.

Seat-Pack QR can be mounted and removed quickly without leaving any residual fixing components on the bike. A special 4.3 cm wide adapter also allows compatibility with dropper posts. Internal reinforcement and compression straps keep the contents tightly packed and securely attached to the saddle and seatpost.

A valve with a grip loop helps compress the bag, while the external elastic cord provides additional storage for gear. A protective plate on the underside prevents damage caused by tire contact and also functions as a fender. Reflective elements improve visibility in low-light conditions.
