Waterproof seat pack with quick release for bikepacking. Hitting the trails on a mountain bike, racing up alpine passes on a road bike, or exploring the unpaved paths on a gravel bike. Whatever adventure you choose, the waterproof Seat-Pack QR is there to accompany you and keep your belongings safe. The innovative Seat-Lock fastening system enables quick attachment, no matter which bike you’re taking out. The fastening system can be removed completely residue-free, and with the help of a special adapter of just 4.3 centimeter in width, this bag can even be used with a dropper post.
The bag’s reinforcement, four compression straps and compression valve ensure that your gear stays in place, and the entire bag remains stable without any swinging movement. Even bumpy and demanding trails are easy to ride without distraction. A protective plate on the underside of the saddlebag prevents damage in case of tire contact and the quick bag attachment and removal are a real asset as well. The bag can be removed from the bike in mere seconds using the levers on the fastening system, and carried into your lodging for the evening with its contents completely dry and dust-free. The roll-top closure promises to keep your belongings dry, even in the foulest weather. Should the 13-liter storage space run out, the elastic cord on the outside allows for the easily accessible stowing of additional items like a vest or jacket. However, the maximum payload of the Seat-Pack QR should not be exceeded. The maximum load of three to five kilograms depends on the position of the hooks on the saddle rails. The PVC-free saddle bag is of course sustainably produced in Germany.

Kätevät mekanismit ja siisti olemus, suosittelen tosin ostamaan isomman mallin jottei tarvitse änkeä.

It took a bit of tinkering to install it under the Specialized TERO X saddle, but it is high-quality and works well. Easy to recommend!

Attaching it is a bit tricky at first, but with a little maneuvering and practice, it slides into place effortlessly even when full (you first need to attach just one of the mounts located under the saddle while the bag is tilted slightly; otherwise, the mount won't fit into the locking position).

You'll have to do a bit of modifying if the saddle is low.

Very sturdy and guaranteed Ortlieb quality, but had to sell and exchange for a 16 liter velcro version because this model was a pain to put on. On the other hand, quick release promises nothing but quick release. Getting the QR teeth around the saddle rails was a pain even in good conditions, so I couldn't imagine using this when hiking and potentially freezing my fingers when putting it on. The velcro version is also sturdy in gravel use and quicker to put on than this one.

The ease of attachment depends quite precisely on the width of the bottom rails of the saddle (the original Cuben saddle is slightly narrow).
The 1 mm throw in the width affected the ease of locking, although it was successful.
Change to a new Gel saddle and the attachment worked smoothly.
