Main fabric : 100.0% Polyester (PES)
To ensure fabrics retain all their initial properties (waterproofing in particular), you are advised not to machine wash, tumble dry, have dry cleaned, or use bleach. Do not iron. To clean your backpack by hand, you are advised to use warm soapy water and a brush if necessary. After a few years, you can refresh the water repellent properties of the fabric using a waterproofing spray.
