High school backpacks

Do you cycle back and forth to school? Then choose a school bag with back ventilation so that your back stays cool. If you use a tablet or laptop at school, choose a backpack with a tablet or laptop compartment to prevent scratches. If your backpack is heavy, it is important that your backpack is comfortable. For extra comfort, choose a school bag with padded shoulder straps and a hip or chest strap. It is useful if a school bag has several compartments, so you can take your things with you.

Perhaps you use a tablet or laptop more often. Then a school backpack of 11 to 20 liters is big enough. These backpacks are compact, but often have extra pockets where you can put your calculator, pens and keys. There are also enough small backpacks with a laptop and tablet compartment.

This is the most common size for backpacks. The bags have enough space, but are not larger than necessary. Most school backpacks have several small pockets. So you never have to look for a pen or your keys for a long time.

Pay attention to your back when carrying so many items. A chest strap and padded shoulder straps ensure that you carry the backpack comfortably. In addition, back ventilation is nice to keep your back cool while wearing a heavy backpack.
