Using this Incase backpack is easy. First, open the main storage area to put in your daily essentials. Place your 15” MacBook Pro gently in the dedicated laptop compartment. You can store small items like keys or cards in the front mesh cargo pocket or back panel security pocket. Use the integrated cable port in the media pocket to connect your devices without taking them out. When carrying, adjust the shoulder straps to a comfortable length and fasten the sternum strap for better support. For maintenance, wipe the backpack with a damp cloth regularly. Avoid using harsh chemicals as they may damage the poly - nylon material. Also, don't overload the backpack to prevent it from tearing or deforming.
