Ortilieb - the best for a reason. Well thought out, well engineered, well made. I would not go with anything less.
I spend a lot of time bicycle touring and use both front and rear panniers. The Ortlieb panniers are the best of ever used.
Well made lite not sure about the color may get dirty quick. I have to decide visibility or dirty bags My wife has black and more stain dirt resistance.
I am touring the Northern Tier this summer and got these panniers in hopes that they would be durable and waterproof and Ortlieb is yet to let me down! This pannier can carry alot and is extremely durable! The outside feels and looks like a rather denim type material but it is 100% waterproof.
The mounting system on these is genious and can really fit any rack. There is a rotatingsliding hook that grabs your rack to prevent it from shaking or sliding. This hook can be removed and put on the second track to cover a range of mounting positions and then tightened to lock in place! This can all be done by hand with no tools!
