Positives: The bags work processes with value and are (with more features) cheaper than the Ortlieb bags. Negatives: The closure system. The upper belt is inserted in the center front. If the bags are not filled to the brim, the connector must be so only fumble into position to insert the belt. On the sides it is similar. Also both lateral straps "male" connector, which is why they can not be interconnected. Thus, an alternative closure and also carrying option is omitted. Property me therefore for Ortlieb (Classic) decided who an elaborate locking system.
