Using this backpack is easy. Just unzip the main compartment and the front pocket to store your items. Slide your laptop into the floating sleeve for safe transport. Adjust the padded shoulder straps to fit your comfort, and if you want extra support, attach the sternum strap. For the water bottle pocket, simply expand it to fit your bottle. When it comes to maintenance, use a damp cloth to wipe the wipeable liners on the front, bottom, and side panels. Avoid overloading the backpack to prevent damage to the zippers and straps. Store it in a dry place when not in use.
