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 usable, 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 note that these are approximate measurements as they were taken by hand. ♦︎ I have washed it with warm water just before listing. ♦︎ The hydration bladder was also only used once, but due to the passage of time, I will not include it for hygiene reasons. If you would like it shipped with the backpack, I will include it for free. Please let me know in a message immediately after purchase. (Use at your own risk.) ♦︎ I am looking to sell this quickly, so please feel free to use the "price reduction request" button or negotiate a price. (However, I may not be able to accommodate requests due to shipping and handling fees.) ※ Please only purchase if you understand that this is a used item. ※ It will be folded in half and shipped in a simple package. ※ Shipping from Okinawa Prefecture may take longer than usual. Please allow extra time for delivery.
