I've been using this for about a year. There are no noticeable stains or scratches, and it's still in good condition. The water-stop zippers also have no peeling. Overview: Product Name: Day Pack 2 X-PAC Size: W305 x H430 x D140 [mm] Weight: Approximately 1,300g This backpack is designed for business use and has multiple pockets for smart organization of small items. It can also store a PC in the cushioned back, and is famous for standing upright on its own. The Day Pack 2 X-PAC uses an orange color scheme to make the contents easy to see, creating a contrast with the black. In addition, by using a different material from the standard DayPack 2, it has increased strength and waterproofness, making it suitable for a wider range of situations.
