Using the Lezyne Flow Caddy is easy. First, decide if you want to use the organized sleeve insert. If so, put it inside the caddy. Then, fill the caddy with your essential roadside repair tools or personal items. When you're on the go, simply attach the caddy to a standard bottle cage on your bike. As for maintenance, after each use, make sure to check the water - resistant threaded lid. If it gets dirty, you can clean the caddy with a damp cloth. Avoid using harsh chemicals as they might damage the caddy. Also, don't over - pack it to prevent any stress on the structure. With proper care, your Flow Caddy will last a long time.
