For commuters who also ride after dark! These waterproof rear panniers with large, highly reflective print are made from robust, PVC-free tarpaulin at our German VAUDE site near Lake Constance using a high-frequency welding process. They can be individually adjusted to just the size you want with their roll closure and are absolutely watertight. Each has an inner compartment with small zip mesh pockets to ensure clear organization. The bike bags are attached to the rear gear rack with the QMR 2.0 system and a sturdy back panel. Just pull the strap connecting the two hooks to conveniently open the system. The system can be secured with a small lock (such as the TSA Lock, not included). It can be easily adjusted with a dial and is completed by the fully adjustable lower rail hook. A practical shoulder strap makes it easy to carry when you're walking. For commuters who are making their way home after dark, these highly reflective bike bags are a must have for the daily journey to the office.
