Using your Incase Staple Backpack is a breeze. First, adjust the shoulder straps to your comfort level. You can place your 15 - inch laptop in the main compartment. Use the smaller pockets to keep your electronics like chargers, earphones organized. The back panel security pocket is great for storing important items like your wallet or keys. When it comes to maintenance, use a damp cloth to wipe the poly - nylon and faux leather parts if they get dirty. Avoid using harsh chemicals as they may damage the materials. Store your backpack in a cool, dry place when not in use. Be careful not to overstuff it to maintain its shape and the durability of the straps and zippers.
