Using this GEOSMINA small handlebar bag is a breeze. To attach it, you can either directly mount it on your handlebar using the fastening straps with metal buckles. Or, if you have a GEOSMINA Harness Roll Bag, you can piggy - back this bag onto it. When packing, open the top roll - up closure and place your items inside. You can use the removable front bungee to secure extra items like a raincoat or a small tool. The adjustable bungee on the top panel can also hold some small things. For better visibility, especially at night, the reflective logo on the bag will help you stand out. As for maintenance, after each use, make sure to dry the bag thoroughly if it gets wet. Wipe it clean with a soft cloth regularly. Avoid sharp objects that could damage the 600D Nylon outer shell or the Hypalon parts. With proper care, this bag will serve you well for a long time.
