this review are premature praise .... my last Vaude panniers-I have at least 13 years, exactly how long I do not remember. I have constantly been in use and thus also handles heavy beverage purchases, etc. regularly. From this incredible life I was so impressed that it necessarily had to be back Vaude bags. The water resistance is also perfect after such a long time. Now slowly come more and more small holes, so I have the new panniers precaution bought before, if it suddenly comes time to end with an old bag. However, I hope that the shifting mechanism of the new bags is no unnecessary weakness. For me, he is superfluous. To me it just depends on the durability, it must be so now prove again .....
