Ortlieb Seat-Pack QR

Ortlieb’s Seat Pack QR is a saddle bag that just doesn’t wobble. It mounts extremely easily via an ingenious yet simple system that clamps to your saddle rails and is compatible with both fixed or dropper seat posts. It's waterproof, has 13L of capacity and the usual Ortlieb signature air release valve.

The bag features the usual high-quality welded construction with a wide opening and easy access waterproof roll-top style closure. That air release valve then helps you roll the bag down tight by releasing any trapped air. It's easy to fit too, but we do recommend checking the handy infographic before purchasing just to check.

The top of the bag has the classic bungee attachment for extra stuff such as waterproofs, there's a plastic skid mudguard on the underside to prevent accidental tyre wear if you mount it too low, a Velcro strap keeper to avoid irritating flapping and reflective detailing on the rear. Everything really has been thought of.

However, the one area where this really shines is its sway-free performance even on arduous off-road terrain. While not the lightest, or the cheapest, the Ortlieb Seat-Pack QR is very impressive being both incredibly stable and a doddle to fit. Our reviewer said buy this if "you want the best non-waggling seatpack out there at the moment."
