Ortlieb Seat Pack

Yes, the Seat Pack is safe to use with carbon seatposts. The mounting system is designed to be gentle on materials, though we always recommend ensuring the contact area is clean before installation to prevent any surface abrasion.

The roll-top closure allows you to adjust the internal volume between 7 and 16.5 liters depending on how much gear you are carrying. By rolling the top down further, you can compress the load to keep it stable, or unroll it to maximize space for bulkier items.

Absolutely. This bag is specifically engineered for bikepacking and touring setups that do not require a rear rack. It mounts directly to your seatpost and saddle rails using secure hook-and-loop straps.

Yes, the Seat Pack is constructed from waterproof, PU-laminated ripstop nylon with an IP64 rating. Because of its position under the saddle, it also functions effectively as a rear fender, keeping mud and water off your back while you ride.

The maximum load capacity is 3 kilograms. Exceeding this weight can cause the bag to sway or affect your bike's handling, so it is best to pack heavier items closer to the seatpost.

The bag features a vertical daisy chain on the rear, which provides a secure and visible attachment point for most standard clip-on rear lights.
