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

A backpack may seem simple to choose, until you have to carry a poorly organised bag every day. A laptop backpack that is too small will not accommodate your work essentials, a heavy hiking backpack is awkward on the train, and a bag described merely as “waterproof” will not always protect you from a heavy downpour.

The following pitfalls are common:

  • Marketing language without clear specifications: terms such as “waterproof”, “durable” or “ergonomic” mean little without information about the material, capacity, dimensions and closures.
  • The wrong capacity: a 10-litre backpack is suitable for daily essentials, but not necessarily for sportswear, a lunch box and documents all at once.
  • Not paying enough attention to carrying comfort: adjustable shoulder straps are useful, but the shape of the back panel, the padding and the weight distribution also determine how comfortable the bag is to carry.
  • A laptop compartment without a suitable size: check the dimensions of the compartment and compare them with your laptop. The stated screen size is not the same as the device’s external dimensions.

Which specifications should you check?

1. Capacity and dimensions

Do not just look at the number of litres. A compact backpack for everyday use with a capacity of 10 to 13 litres may be enough for a phone, wallet, bottle and lightweight jacket. For school, work or a day trip, 20 to 30 litres is often more practical.

Also pay attention to the external dimensions. A bag measuring 45 × 30 × 18 centimetres will have a different layout and fit from a narrow bag with the same stated volume. If you travel by bicycle or public transport, it is worth checking that the backpack remains comfortable within your normal freedom of movement.

2. Water resistance and material

“Waterproof backpack” is sometimes used in product titles for bags that, according to the description, mainly help to resist splashes, rain or dirt. This is not the same as a fully waterproof bag with sealed seams and waterproof zips.

Therefore, check:

  • whether the manufacturer refers to splash resistance, rain resistance or complete waterproofing;
  • which material is used, such as nylon or polyester;
  • how the zips and seams are constructed;
  • which cleaning methods are permitted.

For the Beneunder LC183, the product information states that its protective fabric helps to resist wind, rain and stains. The description also mentions anti-splash protection. Treat this as protection against everyday rainfall, rather than a guarantee against prolonged immersion.

3. Weight, compartments and carrying comfort

A lightweight backpack is comfortable if you carry it frequently. According to the specifications, the Beneunder LC183 weighs 8.3 oz, approximately 235 grams. This low weight can be useful for commuters and travellers who want to keep their luggage compact.

For school or work, a backpack with multiple compartments is often more organised than one large compartment. Check whether there is room for:

  • laptop or tablet;
  • A4 documents;
  • water bottle;
  • charger and accessories;
  • keys and small personal items.

A padded back panel and adjustable straps can make carrying the bag more comfortable. The product descriptions of several models mention breathable mesh or padded shoulder straps. These are verifiable design features; how comfortable a bag feels will also depend on your build, how it is packed and how it is adjusted.

Which type of backpack suits your needs?

A school backpack of around 20 to 24 litres will usually provide more room for books, a laptop and everyday essentials. A travel backpack with a capacity of 30 litres is more suitable for a day trip or short journey, provided the compartments are arranged sensibly. For walking, ventilation, a stable fit and easy access to water are more important than a fashionable appearance alone.

An expandable backpack is useful when the amount you carry varies from day to day. However, pay attention to how the additional space is created: an expandable main compartment can provide more volume, but a full bag may also sit further away from your back. Keep heavy items as close to the back panel as possible.

Frequently asked questions about backpacks

How big should a backpack for everyday use be?

For basic essentials only, 10 to 15 litres may be sufficient. For school or work with a laptop, lunch and documents, around 20 to 24 litres is often more practical. For walks or short trips, 30 litres provides more space. Prepare a trial packing list in advance and check the external dimensions.

How do you clean a backpack?

Always follow the manufacturer's care instructions. For the Beneunder LC183, it is recommended that you wipe the exterior with a damp cloth and leave the bag to air-dry. Machine washing and prolonged exposure to direct heat are not recommended. Do not leave wet items in the bag for extended periods.

Is a waterproof backpack necessary in the Netherlands?

For cycling and commuting, rain-resistant material can be useful. If you carry delicate electronics, you can also use a laptop sleeve or waterproof inner bag. Check whether the product is genuinely fully waterproof or only offers protection against splashes and rain. Understanding this difference helps prevent unrealistic expectations.
