ORTLIEB Seat-Pack QR 13 L is a waterproof saddle bag designed for bikepacking, touring, gravel riding and long-distance cycling adventures. The innovative Seat-Lock mounting system allows the bag to be mounted and removed quickly without leaving any permanent mounting components on the bike.

The abrasion-resistant, PU-coated nylon construction provides excellent durability and IP64 waterproof protection, keeping your belongings dry in heavy rain and splashing water. The internal stiffener and compression straps keep the contents securely packed, while the integrated valve allows the bag volume to be compressed for a more compact fit.

An elastic cord on the top provides additional storage for gear, while the protective plate on the underside helps prevent damage from tire contact and can also function as a rear fender. The Seat-Pack QR is compatible with standard seat posts from 22 to 35 mm and can be used with dropper posts when the included adapter clamp is fitted.
