Using your Incase 13 Reform Backpack is easy. Just unzip the main compartments and put your 13' MacBook Pro, iPad, or other essentials inside. Adjust the padded shoulder straps to fit your body for the most comfortable carry. You can also use the OrthoLite carry handle for short - term carrying. When it comes to maintenance, spot - clean the backpack with a mild detergent and a soft cloth if it gets dirty. Avoid using harsh chemicals as they might damage the 840D Nylon material. Also, don't overstuff the backpack to keep its shape and ensure the longevity of the adjustable straps and the overall structure. Keep it in a dry place when not in use to prevent mold and mildew.
