ORTLIEB Seat-Pack QR is a waterproof saddlebag designed for bikepacking, touring, gravel riding and mountain adventures. Innovative and patented Seat-Lock mounting system provides a secure and stable connection while allowing the bag to be mounted and removed quickly without leaving any fixing components on the bike.

Seat-Pack QR features abrasion-resistant, PU-coated nylon fabric and an internal stiffener that helps keep contents securely packed. Four compression straps provide additional stability and allow the load to be compressed tightly against the saddle and seatpost.

A practical valve with a grip loop makes it easy to compress the bag and reduce its volume. Elastic cords on the outside provide convenient storage for additional equipment, while a daisy chain allows attachment of a rear light or other accessories.

A protective plate on the underside prevents damage caused by contact with the tire and also functions as a rear fender.

Seat-Pack QR is compatible with standard seatposts up to 35 mm in diameter. With the optional adapter clamp, it can also be used with dropper posts featuring 22, 25 or 26 mm tube diameters. The compact adapter requires only 4.3 cm of space on the seatpost.
