Using your Incase Icon Backpack is a breeze. First, place your 15' Macbook Pro in the laptop compartment and your iPad in the internal slip pocket. You can keep your iPhone in the external top - access pocket lined with soft faux - fur. For your small tech accessories like chargers and earbuds, use the organizer pockets in the secondary compartment. The hip - side Power Pocket is great for connecting your portable power bank or audio device. When carrying the backpack, adjust the padded shoulder straps for comfort and use the sternum strap to keep it secure. As for maintenance, wipe the backpack with a damp cloth if it gets dirty. Avoid using harsh chemicals as they might damage the 840D nylon material. Store it in a cool, dry place when not in use to keep it in good condition.
