Using this Hooey backpack is a breeze. First, adjust the padded shoulder straps to fit your body comfortably. You can put your hat on the patented hat strap to keep it handy. For your laptop, slide it into the padded sleeve to protect it. Use the side hydro pockets to hold your water bottles or other small items. The internal organization pocket is great for keeping things like pens, keys, and cards organized. When it starts to rain, quickly attach the detachable rain cover. To keep your backpack in good shape, avoid over - stuffing it to prevent damage to the straps and zippers. Wipe it clean with a damp cloth if it gets dirty. Store it in a dry place when not in use.
