ORTLIEB Seat-Pack QR 13 L is a waterproof and highly durable saddle bag designed for bikepacking, gravel riding, touring and long-distance cycling adventures. The innovative Seat-Lock attachment system allows the bag to be mounted quickly and securely and removed just as easily without leaving any residue on the bike.

Made from abrasion-resistant, PU-coated nylon, the Seat-Pack QR provides reliable IP64 waterproof protection, keeping your gear dry even in heavy rain and splashing water. The internal reinforcement and five compression straps keep your belongings securely packed, while the integrated valve allows the bag volume to be compressed.

An external elastic cord provides additional space for carrying extra gear. The protective plate on the underside helps prevent damage from contact with the rear tyre and can also function as a rear fender. The included adapter clamp allows the bag to be used with compatible dropper posts.
