This is a CamelBak hydration pack with a hose. I purchased it new in July 2023 and used it twice for tent camping: once in August 2023 and again in August 2024. I only used it to carry spare water in the main body, so the hose is unused. After August last year, I sterilized, washed, disinfected, and thoroughly dried it before storing it in a simple moisture-proof storage. * Although it's been almost two years since I purchased it, it's in excellent condition with almost no stickiness or noticeable stains, and I think it can still be used for a long time. However, since it has been used once by someone else, I would appreciate it if those who understand that it is a USED item would consider purchasing it. ⚠ There are no smokers in my household, nor do we have any pets. - Brand: CamelBak - Color: Blue - Type: Hydration Pack - Accessories: Hose (unused) - Capacity: 2L ⚠ Shipping will be as thin and small as possible.
