This backpack was only used a couple of times when my child was in lower elementary school for ski trips. Size: Approximately 35cm tall, 31cm wide, and 22cm deep. It's a good size for a lower elementary school child to carry. There is one pocket on the front, and a section on the right side for ski boots (see photo 3). There is also space on top for a lunchbox, separate from the ski boots (see photo 4). Thank you for looking.
