Summary of Reviews

We have read all expert and user reviews on the ORTLIEB Seat-Pack. In summary, this is what cyclists think.

9 reasons to buy

The Seat-Pack comes in two versions: regular (11L or 16.5L) and QR (13L). The latter has a quick-release mount.
Long-term testers and owners praise the quality of the Seat-Pack, with some using it for up to five years.
Experts say both mounting systems effectively prevent side-to-side sway.
Testing shows that the bag remains stable over rough off-road terrain.
Reviewers appreciate the ease of use of the Seat-Pack QR.
In testing, the bag endures prolonged exposure to heavy rain without water ingress.
The Seat-Pack has an air-release valve for better compression when packing.
The QR version comes with adapters that render it compatible with dropper posts.
ORTLIEB sells replacement parts for this bag.

3 reasons not to buy

Determining saddle compatibility with the QR mount is tricky, and it's not compatible with carbon saddle rails or sprung saddles.
Testers say the 16.5L size sags when “stuffed” full, and the support strap costs extra.
At 1.38lb, the Seat-Pack QR is heavy for a 13L saddle bag.

Bottom line

ORTLIEB’s Seat-Pack is a roll-top saddle bag offered with a standard hook-and-loop mount (11L or 16.5L) or a heavier quick-release mount (13L). Both are praised for their stable, saddle-hugging fit, long-term durability, and reliable waterproofing. The QR model is easiest to remove but has reduced saddle compatibility. Dropper posts are fine, though both versions require adequate seatpost clearance. The 16.5L size can sag, so the optional support strap is recommended. Overall, experts and owners find few flaws in the ORTLIEB Seat-Pack and consider it a solid investment.

ORTLIEB Bikepacking Bags Review! 6 Months of Use – How Are They?!

Level 1 expert

If they put some sort of reinforcement or some firm strip of plastic up the inside to help it hold its shape and rigidity when it was on the bike, that would be perfect.

Apidura and Alpkit’s seat packs are even lighter and cheaper too, so the QR convenience comes at a serious weight and cost penalty if you don’t need it.

Level 5 expert

While not the lightest or the cheapest, the ORTLIEB Seat-Pack QR is very impressive, being both incredibly stable and a doddle to fit. The only downside is that it doesn’t fit all saddles…

Review: ORTLIEB Seat-Pack and Frame-Pack RC Waterproof Bikepacking Bags

Level 5 expert

Bottom line, the Seat-Pack is not for everyone, given the clearance limitations and weight distribution, but it does hold an advantage of utilizing available space somewhere besides the frame or handlebars.
