This backpack pad keeps the space between the hot backpack and your back comfortable. This one has a purple-based floral pattern with purple bias tape. It's made with a honeycomb fabric with a three-dimensional structure like a beehive, creating air passages to prevent stickiness, and providing excellent cushioning. Since this fabric is used in two layers, it's not flimsy, but durable and fluffy. It can be easily attached with elastic and hooks. It can be attached to backpacks without a bottom rim, and to larger A4-size backpacks. Please check the size in the images before purchasing. My daughter, who started first grade, developed a bruise near the shoulder straps, so I initially made this to improve the cushioning on her back. It has two pockets, and at our house, we fold a quilt batting and put it in the upper pocket to prevent the shoulder straps from directly touching her. My daughter says it doesn't hurt anymore! and she uses the backpack pad every day on her way to school. In the hot season, we put a non-freezing type of ice pack in the lower pocket. (The ice pack in the photo is 10cm long x 16cm wide x 1.5cm thick, and weighs 150g. If you would like to include an ice pack, it will be sold for 450 yen. It can be included, so please comment before purchasing.) In the cold season, we put in a body warmer. I hope your commute to school will be a little more comfortable! *Since some parts use elastic and hooks, please hand wash with household detergent when washing, or wash in a laundry net if using a washing machine. *The elastic, bias tape, and plastic snaps are made in Japan.
