nice thick canvas. excellent quality. I have found in the past that the military canvas backpacks last for years! My older son still has his and I am hoping this lasts just as long for my younger! Will not purchase the usual backpacks anymore. They rip, zippers break, boys drag them and the nylon shears off! Canvas is the way to go, and they love the "cool" military style....
