This is a limited edition Camelbak backpack, likely ordered by a U.S. Navy unit about 13 years ago. I only used it once for hiking, but it has been stored in the garage for many years, resulting in discoloration and various stains. It's tough and still functional, but please be aware of the overall dirt, discoloration, and peeling of the inner coating before purchasing. Size: Height: 44cm x Width: 24.5cm x Thickness: 5cm * Please consider these measurements as approximate, as they are based on personal measurement. ♦︎ Washed with warm water just before listing. ♦︎ The hydration bladder was used only once, but due to hygiene concerns and aging, it is not included. However, if you wish to have it included, I will provide it free of charge. Please let me know via message immediately after purchase. In that case, please inspect it thoroughly before use. ♦︎ (Although it may be difficult due to shipping and handling fees,) I want to sell it, so feel free to use the "price reduction request" button or negotiate the price. * Please only purchase if you understand that this is a used item. * It will be folded in half and shipped in simple packaging. * Shipping from Okinawa Prefecture may take longer than usual. Please allow extra time for delivery when purchasing.
