With back-to-school just around the corner, it’s time to check backpacks, refresh supplies, and make sure the little ones (and not-so-little ones) have everything they need to start the school year full of energy.
A well-equipped backpack not only helps with organization, it also helps students feel more confident, motivated, and ready to take on the classroom each day.
In this article, we’ll tell you what’s essential, how to organize everything in a practical way, and of course, how to choose the best reusable bottle according to age and needs.
What should a well-equipped school backpack have?
A good school backpack isn’t judged just by its design or brand. What’s most important is that it’s functional, ergonomic, and has the right compartments to organize everything in its place. But… what should you carry inside?
- Pencil case with basic supplies: pencils, pens, eraser, pencil sharpener, markers, small scissors, and glue stick. Depending on the grade, also a compass, ruler, or calculator.
- Notebooks and folders: ideally lightweight and specific for each subject. Folders with dividers can be a practical option for older students.
- Planner or organizer: essential for encouraging organization from a young age. Writing down homework, tests, or activities helps with time management.
- Healthy snack or lunch: a piece of fruit, nuts, or a light sandwich helps keep energy up throughout the day.
- Reusable water bottle: essential for staying hydrated, especially if they spend many hours away from home or have sports activities. Further down we explain how to choose the most suitable one from among our stainless steel bottles for kids.

Back-to-school essentials checklist
If you need a quick checklist to make sure you don't forget anything important in your school backpack, here's a basic list:
- Complete pencil case
- Notebooks or exercise books
- School planner
- Healthy lunch
- Reusable water bottle
- Tissues
Remember that the more personalized the backpack is to the needs of the child, the more efficient it will be. For example, if they have after-school activities, they might also need a change of clothes or a toiletry bag with a comb and deodorant.
How to choose the ideal bottle by age
Not all bottles are the same, and not all children need the same one. Here are some key tips for picking the perfect water bottle for school:
Preschool (ages 3–6):
- It should be lightweight and easy for them to open and close by themselves.
- Preferably with a straw or ergonomic spout.
- BPA-free and impact-resistant material.
- Capacity: between 260ml and 350ml.
- Attractive design, with colors or characters that motivate them to use it.

Primary (6-12 years old):
- We’ll look for more durable bottles with a good capacity, such as 500ml.
- That keep water nice and cold, especially during the hotter months.
- Stainless steel to avoid any aftertaste.
- Screw cap or flip-top, depending on preference.

- Ideally, the bottle should keep drinks cold for many hours.
- Capacity: between 500ml and 750ml.
- If you play sports, it’s recommended to choose a bottle suited for that purpose.
