Using this seat pack is a breeze. First, use the Boa® fit system to attach the pack to your bike's seat post. Simply turn the dial to tighten or loosen for a perfect fit. When packing, you can put small items like tools, snacks, or a rain jacket inside. Make sure not to overfill it as it may affect the stability on your bike. To keep it in good condition, clean it with a mild soap and water after getting dirty. Avoid using harsh chemicals as they might damage the waterproof coating. Store it in a dry place when not in use.
