Get ready for your next bikepacking adventure! As a key item in your bikepacking setup, the ORTLIEB Seat-Pack comes with Velcro straps to enable convenient and secure mounting to your seat stem. Projecting backwards from the seat stem, your Seat-Pack also serves as a rear fender. The spacious, waterproof Seat-Pack keeps its contents (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 7 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 mountain bike. The Seat-Pack is available in two sizes.
Thanks to its elastic drawstrings on the top it offers additional space for items you need to be able to access quickly (not on 11l slate version).
The smaller of the two models needs only six centimeters on your seat stem. That’s why the more compact model is ideal for smaller frame sizes, full suspension bikes and adjustable seat stems.

Works as expected and at the very least significantly lightens the backpack, if not completely eliminates the need for it. The fastening straps that come around the seatpost are reasonably stiff, so it takes work to get them taut at the very end. Sometimes I even wonder if I should have invested more in that Boa roll-tightening model. I don't know the method used to measure the volume. I bought this locally so the available space was visible. When read on the screen, 16.5 l may sound large, but in reality it is not.

One trip behind and based on that, I could also buy the bag again. The bag fits well and stays firmly on the seatpost quite stable. The bag can be tightly packed by squeezing out excess air through the air valve, even if the bag is not full. It requires a little adjustment and tightening of the straps when attaching and removing the bag from the bike, but the system is functional. When fully packed, a tensioning strap sold separately is necessary.
