Color: Gray. Dimensions: 36cm wide, 28cm high, 15cm deep, base 12cm. Never used. It's very clean. Inside, there are three pockets, and I think you can also stand up a water bottle or umbrella. There are also two zippered pockets in the front and one in the back, and pockets on the sides. Also, when you close the large zipper, items can be put in from the side. Please check the photos. The size was measured by an amateur, so there may be some slight variations, but it's good for a one-night trip as it can hold a lot. I would be happy if you like it. Also, please note that returns are not accepted. The material is nylon and very light. I have taken a photo of the material, so please take a look.
