Using this Incase Icon backpack is a breeze. First, put your laptop in the dedicated laptop compartment. Make sure it fits well and is secure. You can place your iPad in the internal slip pocket. Your iPhone can go in the external top - access pocket with the soft lining. For small tech accessories like chargers, cables, and earbuds, use the organizer pockets in the secondary compartment. If you want to use a portable power bank or listen to music, connect them through the cable port in the hip - side Power Pocket. When carrying the backpack, adjust the padded shoulder straps to your comfort level and fasten the sternum strap for a secure fit. To keep your backpack in good condition, avoid overloading it as it may damage the compartments or the zippers. Wipe it with a damp cloth regularly to clean off dirt. Don't expose it to extreme temperatures or sharp objects that could tear the 840D nylon material.
