It uses CORDURA EcoMade canvas, and its characteristic weave has a bumpy texture like canvas, making it lighter, more durable, and tough. It's also treated with Teflon, providing water repellency and stain resistance. The inner mesh pocket now has two floors, making it easier to store items like water bottles. Also, switch colors have been introduced for the first time this time. The actual product has a very nice atmosphere. The pocket gussets are box-shaped like those of Eastpak, and while the functionality remains the same, it's a detail that will appeal to vintage clothing enthusiasts.
