Afternoon Tea LIVING Zero Gravity Backpack, Black, Medium Size. Water-repellent, with a back designed to prevent stuffiness. It is said that the AGS function absorbs the impact of walking and reduces the burden on the body by 43%. There are two pockets on the front, one on the back, and three inside. Used only once. When I actually wore it, it felt light, and the weight wasn't that noticeable even though I had a lot of luggage in it. Please note that it is not new. Thank you for looking.
