Hi, here's some info. on the body of the bag. The material is very sturdy.
CANVAS & PVC - From the care card: The material used for this product is the result of a long manufacturing process which combines a layer of canvas with one of PVC. It is a technical material extremely resistent to wear and tear but sensitive to heat and cold with a tendency to soften or stiffen respectively. Wash with neutral soap and water. Do not use alcohol or solvents.
Thank you so much!
