Ortlieb Seat-Pack L – 16.5L


4.86 (7 reviews)

Get ready for your next bikepacking adventure with an ORTLIEB Seat-Pack. It 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. You can adjust the volume of your 16.5L seat pack from 8 to 16.5 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. Thanks to its elastic drawstrings on the top it offers additional space for items you need to be able to access quickly.

    This is superb. Stays put, fits a lot, very waterproof, looks great. Very happy. Will be putting to the test over summer.

    Excellent seat pack- a bit fiddly to fit to seat but worth the effort for a lighter weight bag

    Well made product. Attachments fits well to seat post. Minimal to no movement sideways when cycling.
    The optional strap to stop the pack from sagging should be part of the pack from the start. Pack deserves a 5 but selling the strap as a extra! pulls it down
