This is a mother's backpack purchased from Akachan Honpo. I used it about twice, but haven't used it since then! The main body is made of lightweight nylon with a water-repellent finish that repels rain and dirt. It has a total of 10 convenient pockets on the outside and inside. The shoulder straps have convenient buckles, allowing you to take it on and off while wearing it. It can also be attached to a stroller with the hooks (removable) attached to the top and both sides. It has a handle on the top, making it convenient to carry. There is a zippered opening on the back, allowing you to take things in and out of the main body while wearing it. The back is made of breathable mesh. ・Material: Nylon water-repellent finish ・Size: Height 400mm, Width 280mm, Depth 140mm ・Weight: Approximately 520g ・Backpack body with handle ・Mesh back ・Zippered opening on the back ・Hooks on the top and both sides (removable) ・Shoulder strap buckle ・10 pockets in total (inside and outside)
