This is a Timberland body bag. I bought it but haven't used it. It has a pocket on the side of the main pocket that can hold a smartphone, etc., making it easy to use. The main pocket is about 13 cm tall and 18 cm wide, and the overall width is about 35 cm. There is a pocket with a zipper on the back. It comes with an adjustable strap and can also be used as a waist pouch. Thank you for looking.
