To use this saddle bag, first attach it to your bike seat using the quick - release mount. Make sure it's firmly secured before you start your ride. When packing, put your essential items like keys, phone, or small repair tools inside. Remember, it's designed for just the necessities, so don't overstuff it. For maintenance, wipe it down with a damp cloth after each ride to keep it clean. If it gets really dirty, you can hand - wash it with mild soap and water. Avoid using harsh chemicals as they might damage the Teflon - coated nylon. Check the 3M reflective strip and taillight clip regularly to ensure they're in good condition for your safety at night.
