ORTLIEB Seat-Pack is a spacious waterproof saddlebag designed for bikepacking, alpine crossings and touring. With an 11 L capacity, it provides convenient storage for clothing and other essential gear while keeping the contents protected from rain and moisture.

The bag attaches securely to the seat post using strong hook-and-loop straps and extends backwards from the saddle to provide additional protection from spray, allowing it to function as a rear mudguard. The roll closure can be adjusted to adapt the volume to the amount of gear being carried.

An integrated air-release valve allows trapped air to be quickly expelled, making it easier to compress soft gear for a compact fit. The sturdy PE inner stiffener provides additional stability, while reinforced fabric at the saddle-rail mounting area increases durability.

The Seat-Pack can also be mounted to carbon seat posts and is suitable for round seat posts with a maximum diameter of 34.9 mm. A Daisy Chain on the underside allows a rear light to be attached, while external elastic cords provide convenient storage for additional equipment.
