Description The Ortlieb Seat-Pack fully waterproof bikepacking saddle bag that is attached via buckles & straps and comes in 11L or a massive 16.5L size. This saddle bag comes with Velcro straps to enable convenient and secure mounting to your seat post. Projecting backwards from the seat post, your Seat-Pack also serves as a rear fender. This spacious, waterproof saddle bag keeps your gear (e.g. an extra set of clothes) safe and dry. Depending on how long you plan to be away and your Seat-Pack model, you can conveniently adjust the volume of your pack from 8 to 16.5 liters or from 4.5 to 11 liters by adjusting the roll closures on the sides. An additional valve allows you to quickly and easily compress your soft gear for a more compact fit. Your Seat-Pack also serves as a replacement backpack when you’re out on a day trip, no matter whether you ride a hybrid bike, a mountain bike, a road bike or an electric dually.
