Using this backpack is easy. First, place your 17' laptop in the padded sleeve for a secure fit. You can store your iPad in the inside slip pocket. Put chargers, cables, and other small essentials in the organizer pockets. When packing for a longer trip, expand the main compartment to increase the capacity. To carry it comfortably, adjust the padded shoulder straps. When using it in bad weather, the weather - resistant front panel will protect your items. For maintenance, simply wipe it clean with a damp cloth. Avoid using harsh chemicals. Make sure to secure the side compression straps to keep the contents stable while carrying.
