This is a handmade item. The outer blue fabric is cotton, the bottom is plain canvas, and the inside is quilted. The size is: height 30cm, width 42cm, gusset 15.5cm. Please note that there may be slight variations due to amateur measurements. There are two inner pockets. It also has a D-ring, so a shoulder strap can be attached. The shoulder strap is not included. I used it once for testing, and it has been washed. It's a large size, so it's recommended for one or two-night trips. It will be shipped folded. I make it carefully, but since it's handmade by an amateur, there may be some stitching errors or distortions. I appreciate your understanding. Thank you for viewing my item from among many others.
