I bought this for a trip and used it for about two days while traveling, and it's generally clean. A 500ml plastic bottle fits easily in the side pocket. The bag has thick straps that are comfortable on the shoulders even when the bag is heavy, providing peace of mind. It's perfect for travel, leisure, and even as a campus bag. Bag size: Width 43cm (bottom width: 31cm) Height 33cm, Depth 14cm Color: Cream Material: Nylon
