Using this seat bag is a breeze. First, open the bag and neatly place your items like road tubes, multi - tool, tire levers, and the inflator with cartridge inside. Then, use the dual - sided seat post hook & loop strap to attach it to your seat post. Make sure it's secure so it won't fall off while you're cycling.
When it comes to maintenance, if it gets dirty, simply wipe it down with a damp cloth. Since it's water - resistant, you don't have to worry too much about light rain, but try to avoid submerging it in water for a long time.
Also, be careful when attaching the strap to your seat post not to scratch or damage your bike. And always check the strap's tightness before each ride to ensure the bag stays in place.
