Using your Birzman Packman Handlebar Pack is easy. First, attach it to your handlebar using the three - point attachment system. Make sure it's secure for a stable ride. Adjust the capacity of the roll - top IPX5 waterproof carrier according to your needs by rolling it down. You can use the two extra straps to attach additional items. When it comes to maintenance, clean the pack with a mild detergent and water. Avoid using harsh chemicals that might damage the fabric. After cleaning, let it dry completely. Keep it away from sharp objects to prevent abrasion. Store it in a cool, dry place when not in use.
