4.5 (4 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 11L seat pack 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. Thanks to its elastic drawstrings on the top it offers additional space for items you need to be able to access quickly.  This model needs only six centimeters on your seat stem so is ideal for smaller frame sizes, full suspension bikes and adjustable seat stems.

Use with Wolf Tooth Valais Dropper Post Bag adapter on dropper seat posts.

    Have used this once and heaps of room. It would be good to have a removable dry back so I did not have to undo all the straps. Good Size no sway.

    Very good overall, few minor improvements could be made – the orange bungie on the top should be further back along the bag – some of it is under the seat so obsolete. The front is a little wide between the legs (can feel on inner thigh occasionally when cycling) This does not work with a dropper post (you get about 4cm drop then the wheel hits the bag)

    Was an excellent bag. Great features and size for bike packing. Didn’t buy this as the Revelate one fitted my bike better
