Using this bag is easy. First, attach it securely to your seatpost. You can put all your essentials like clothes, snacks, and a small repair kit inside the 15 - litre compartment. Use the bungee cord on top to store items like a raincoat or a hat. When riding, thanks to its anti - sway design, you don't have to worry about it swinging around. As for maintenance, after a muddy ride, rinse it with clean water and let it dry. Avoid using harsh chemicals as they may damage the waterproof coating. Make sure to check the attachment regularly to ensure it stays tight.
