Your other choice is a briefcase with wheels. This is my favorite because you can organize your school supplies, books, notebooks and even your pocket space that can further protect your laptop. There are lots of backpacks to choose from, but the problem is the best for you. The weight of a normal backpack should not exceed 15% of the total weight (Singh and Koh). If the student's weight is 140 pounds, do not have more than 21 pounds backpack (Avantika Rai).
If you are permitted at school, please consider rolling backpack. This type of backpack is a good choice for students who have to load heavy luggage. Keep in mind that rolling backpacks still need to climb stairs, they may be hard to roll in the snow, and they may not be suitable for some lockers . Please check the safety of your child and your backpack. If your child's school bus has a knee belt, please make sure that your child is using one on the bus at all times. (If your child's school bus does not have knees / shoulder straps, we recommend buying or renting a bus with a knee / shoulder strap in the school system.) For details, please see the school bus safety restrictions.
I currently use LL Bean's large rolling duffle bag and Kelty 40L backpack (the biggest backpack you can carry with you). The backpack also serves as a traveling bag and has spent two weeks, so it is a very convenient and faithful backpack. When I settled down somewhere in the suitcase, I packed daily bags and laptop bags in daily necessities.
Backpack students can not bring backpacks into the classroom. If you can store it in a locker instead of keeping it on a locker during school you can use a backpack to put the book in and out of school. The hallway must always be open. An athlete should place a gym bag in the locker room during class hours. The lost aisle is important. If students lose something or discover something, please contact the school. If you find your iPad in your spare time, please let your faculty and staff know. The lost-item table is in the dining room. Unclaimed items will be offered to the executive at the end of each quarter
