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 litres or from 7 to 11 litres 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, the 16.5-litre model offers additional space for items you need to be able to access quickly. This model needs only 15 centimetres of space on your seat stem.

The smaller of the two models needs only six centimetres on your seat stem. That’s why the more compact model is ideal for smaller frame sizes, full suspension bikes and adjustable seat stems.

Further Features:

Reinforced fabric at all points of contact to the seat

Vertical daisy chain for rear light

Also suitable for carbon seat stems

Lightweight design

Four 3M Scotchlite reflectors available for full extension

Absolutely perfect!

That bag is amazing. I use it for my work commute, it fits my uniform and lunch. Easy to remove and install. Doesn’t juggle around while I ride. No complaints. Definitely work the price.

Awesome pack

Bought it for a 6 day cycling tour in the Central West of NSW.

Ortlieb seat pack did exactly what I expected it to do. Lightweight, waterproof, easy to install, stay firmly secured in position during the ride.

Highly recommend it.
