Using this Incase Icon backpack is a breeze. First, unpack it and you'll notice all the compartments. Put your 15 - inch Macbook Pro in the laptop compartment and your iPad in the internal slip pocket. Your iPhone can go in the external top - access pocket with the soft faux - fur lining. Tech accessories and small items should be stored in the organizer pockets of the secondary compartment. You can connect your portable power or audio devices through the cable port in the hip - side Power Pocket. When carrying, adjust the padded shoulder straps for the best comfort and fasten the sternum strap for a secure fit. As for maintenance, keep it away from sharp objects to avoid tearing the 840D nylon. If it gets dirty, use a mild detergent and a soft cloth to clean it. Let it air dry thoroughly before using it again. And remember, don't overstuff it to keep the shape and ensure long - lasting use.
