Using this Apidura musette bag is a breeze. First, attach the integrated on - bike pocket to your bike frame using the included velcro strap. This will keep the bag out of the way when it's not in use. When you need to use it, simply unpack it from the on - bike pocket. You can put your food, tools, or other essentials inside. The 7 - litre storage space is quite roomy for your mid - ride needs. Make sure to close the bag securely with the velcro flap.
As for maintenance, since it's made of waterproof materials, you can easily wipe it clean with a damp cloth after a dirty ride. Avoid using harsh chemicals as they might damage the ultralight fabric. Also, check the velcro regularly to ensure it's still sticky enough to keep the bag closed. When packing it back into the on - bike pocket, try to fold it neatly to save space. Remember, the reflective details on the rear are there to keep you visible at night, so keep them clean too.
