Using your Arkel water - resistant frame bag is a breeze. First, decide on the size that fits your bike frame best from the 2.5 - liter, 4 - liter, or 5 - liter options. Open the large opening and pack your tools, food, or extra clothing inside. Use the air pump attachment straps on the upper part of the bag to secure your air pump. To attach the bag to your bike, use the attachment straps and the daisy loops system. You can adjust the position of the straps using the daisy loops to make sure the bag fits your frame perfectly and stays under tension. You can also use the daisy loops to secure other items like tent poles or fishing rods. When it comes to maintenance, since it's water - resistant, a simple wipe - down with a damp cloth after getting dirty should do the trick. Store it in a dry place when not in use. Avoid using harsh chemicals on the bag, as it's made of X - Pac carbon neutral and waterproof fabric and Cordura 1000D, and these chemicals might damage the materials.
