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.

Smaller than I thought (11L) but works well. Rainproof, quite stable on the bike. A bit tricky to get it in place with my saddle, so not something you want to take off and put on.
Works well as a mudguard.

Nice color and high quality bag. Fits a change of clothes for a trip, for example. Attaches to the seatpost and saddle, so it's not very easy to remove and install. However, the bag stays in place well when installed correctly.
In hindsight, I would have taken a larger size bag, this one fills up quickly.

I think the Ortlieb Seat-Pack 11 L is an excellent saddlebag that is definitely worth the price. Although this model is a bit more expensive, it stays really firmly in place even in rough conditions, and doesn't wobble or interfere with riding.
The volume is just right for longer trips, and the waterproof material keeps your gear dry in all weathers. It's easy to assemble, and the bag feels very high quality and durable. If you need a reliable saddlebag, this is definitely a good choice. ⭐⭐⭐⭐⭐

A good and sturdy saddle bag. Moderately small, but perfect for light camping.
