Thank you for viewing. I purchased this at Kojitsu Sanso and used it several times for mountain climbing, after which it was stored at home. This item was used by a child, so please understand that it is a used item. There is a name written on it, which will be covered up before delivery. An おしゃれ (oshare - stylish) kids' backpack that rivals adult ones has arrived from "MAMMUT," a full-fledged mountaineering equipment manufacturer originating from Switzerland. The 18L size is perfect for elementary school students in the lower grades to middle grades. It can neatly store lunch boxes, water bottles, and A4 notebooks!! It's also recommended for bags for extracurricular activities. For peace of mind and safety, it comes with a name tag & reflectors. Furthermore, it has a chest belt, which is essential for children, to prevent it from slipping off. The belt position can be adjusted up and down. Also, a security whistle is included to be useful in case of emergency! The back and shoulder straps have cushion padding and breathable mesh material. It provides a comfortable carrying experience even when moving actively. Full-fledged features such as a hydration system, trekking pole carrying, and a waist belt. ■Size: Approximately W30 x H56 x D28 (cm) ■Capacity: Approximately 18L Mammut MAMMUT First Trion 2510-03110 0575 black-inferno 18L [Kids' Bag] Travel, forest school, summer camp, summer school, overnight childcare
