Using these DXE MX bags is a breeze. First, make sure you have a suitable mounting rack, like DXE's MX Rack, and attach the bags securely to it. When packing, you can easily load your items into the 6.5 - litre capacity bags. The waterproof PVC lining means you don't have to worry about your stuff getting wet in the rain or if there's a splash of water on the road. For safety, the reflective patches on the bags help you be more visible, especially when riding at night. As for maintenance, just wipe the bags down with a damp cloth after use to keep them clean. Avoid using harsh chemicals as they might damage the PVC lining. And when not in use, store the bags in a dry place to prolong their lifespan.
