Product Details Top Highlights Brand: CamelBak Color: Blue Material: Polyurethane (PU) Sports: Motorcycling, Cycling, Mountain Biking, Running, Climbing Item Weight: 0.24 kilograms Capacity: 3 liters Reliable technology backed by history. A traditional model that has been steadily improved and evolved. Reference weight: 3L = 235g Easily switch the mouthpiece on/off with the valve lever. Amazing durability that passes durability tests in our own lab. Holds up to 3 liters. Please judge the dimensions from the photos. Since it's unopened, I don't know the dimensions after water is added. My American husband purchased this in the US some time ago, and it has been stored at home in Japan, but it hasn't been used, so I'm putting it up for sale. Since it has never been used, the tip of the tube has a plastic cover on it. I would appreciate it if those who understand that this is a used item would purchase it. Currently, it seems to cost around 7,000 yen to buy the same item on Amazon. CamelBak is a company headquartered in California, USA. As a specialized manufacturer of hydration systems, it is known worldwide, and is a brand with high reliability and innovation, with its products officially adopted by the US Army, as well as for cycling and outdoor activities. This company was the first to create and sell hydration bags. Thank you for your consideration.
