In order to preserve the fabrics' properties (including waterproofing), do not machine wash this product, do not tumble dry, do not dry clean and do not use bleach. Do not iron. To clean your backpack by hand, use warm soapy water and a brush if needed. After several years of use, you need to restore the water repellent properties of the fabric with a "waterproof" spray.
