Buying a backpack: how to choose a practical model for school, work or travel

Buying a backpack sounds simple, until you find yourself dealing with an opening that is too small, a vulnerable laptop compartment or books soaked through every day. Students, pupils, professionals and travellers often focus mainly on colour and price. However, the key differences lie in size, layout, material and carrying comfort.

When comparing a laptop backpack, school backpack or travel backpack, pay particular attention to these three pitfalls:

  • “Water-repellent” is confused with waterproof. A water-repellent backpack will usually keep out light rain more effectively, but seams and zips can still let moisture through during prolonged, heavy rain.
  • A stated laptop size is not always unambiguous. Check the dimensions of the compartment, rather than just the “15.6-inch” designation. A laptop with a wider body may otherwise not fit.
  • A large capacity does not automatically mean practical use. A large backpack without compartments can become difficult to organise. For everyday use, separate compartments for your laptop, charger, bottle and small accessories are often more convenient.

Which specifications should you check before buying?

1. Laptop compartment and internal dimensions

If you are looking for a backpack with a laptop compartment, check your laptop size first. As well as the screen diagonal, look at the dimensions of your device. A 15.6-inch laptop is not always the same width or depth.

A side zip can be useful when you want quick access to your laptop while on the move. For school or work, a padded laptop compartment and space for a charger, documents and a lunchbox are also practical. If the description only says “laptop compatible” without providing further information, it is sensible to check the product dimensions with the seller.

2. Material and water resistance

A water-repellent backpack is suitable for short bike rides in light rain, but not automatically for prolonged exposure to heavy rainfall. Look at:

  • the material used, such as polyester, canvas or 900D fabric;
  • the finish on the outside;
  • the construction of the zips and seams;
  • the care instructions;
  • whether the product warning states that the model is not fully waterproof.

According to the product description, the NINETYGO backpack is made from 900D tear-resistant fabric and has a level 4 water-repellent finish. The same description also states that the bag is not fully waterproof and should not be exposed to heavy rain for prolonged periods. This is a clear distinction between water-repellent and waterproof.

3. Dimensions, capacity and carrying comfort

A large backpack provides plenty of space, but can become heavy when filled completely. Therefore, check the dimensions and make sure the shoulder straps are adjustable and padded. A padded back panel can improve carrying comfort, while a chest strap or wide straps may provide additional stability for some users.

For a backpack for work, a professional layout, quick access and a trolley sleeve are useful. For a backpack for school, space for books, a drinks bottle and a laptop or tablet is particularly important. If you are looking for a backpack for women and men, it is better to focus on adjustability and actual dimensions than on general size labels.

Also look out for product information that contradicts itself. The description of the NINETYGO College-Style Dual-Shoulder Backpack mentions a laptop of up to 15.6 inches, while the specifications table states compatibility up to 14 inches. Check this before ordering if your laptop is larger.

Caring for your backpack and extending its lifespan

A backpack’s lifespan depends on its load, material, fastenings and care. Do not overfill it: an overloaded main compartment puts strain on zips, seams and shoulder straps. Clean stains according to the care instructions. For the NINETYGO backpack, hand washing and air drying are recommended; machine washing and tumble drying are not advised.

Do not leave wet items in a closed bag for long periods. A wet umbrella should go in a suitable side pocket or a separate cover. Also check the zips, base and seams regularly. Small signs of damage are easier to spot before they become more serious during a bike ride or journey.

Frequently asked questions about buying a backpack

Which backpack is suitable for school?

For school, a model with enough room for books, a laptop compartment, a drinks bottle pocket and adjustable shoulder straps is practical. A compact children’s backpack, such as the PUMA Phase Small Backpack, has a capacity of 13 litres according to the product information. For secondary school pupils carrying books and sportswear, a model of approximately 24 litres may be more suitable.

Is a water-repellent backpack suitable for cycling in the Netherlands?

A water-repellent backpack may be suitable for short rides in light rain. For prolonged or heavy rain, a rain cover or fully waterproof bag is a wiser choice. Always check the product warning: “water-repellent” does not automatically mean that your laptop, books and clothing will stay dry in all conditions.

How many litres should a work backpack hold?

That depends on what you carry. If you only need to take a laptop, charger and a few documents, a compact laptop backpack may be sufficient. If you also carry lunch, clothing or accessories, it is better to look for a larger backpack of around 20 to 25 litres. As well as capacity, consider the layout, because a well-positioned laptop compartment can be more important than extra unused space.
