Very good quality

This bag is made with quality in mind. It's just the right size for a day ride, possibly an over-nighter, or to carry your work or gym stuff. The extendable side compartments are big enough to hold a jacket and more. It looks like it could take a few knocks, no problem, without tearing or coming loose. Like previous reviewers said, the straps to attach it to the rack aren't the best but they do the job. I'm happy with it.

Good value and attractive unit, but...

High quality and well designed, except Velcro straps rather fiddly and too long.
Concerning that warranty misleads customers about their rights under Australian Consumer Law, to a return or refund. Sought explanation from company but no response.
