I have used a set of Nashbar front panniers on several tours, including a ride across the U.S. Even though I have replaced the Nashbar bags for touring with Ortlieb bags after about 2 years of use, I still use the Nashbar bags almost every day (last 8 years) for riding to the gym, store, post office, library, etc. They are still waterproof, and function reasonably well. I did modify the attachment system with higher grade bungees and hooks.

However, IMO the Nashbar product does not compare with the the quality or durability of Ortlieb panniers. I believe that if a person is really sure they want to use panniers for the long run, getting a quality set is a good investment.

The reason I went with the Nashbar front panniers to start with was my uncertainty about using front panniers. Once I knew they fit well in my gear options, I upgraded to a better set.

Bottom line is: Nashbar panniers are good enough to meet most people's need, at a reasonable price.
