Choosing bags and backpacks without costly mistakes: a practical guide for every day

A bag should suit your daily routine. Yet many shoppers focus mainly on colour, price or an eye-catching product photo. As a result, a model may turn out to be too small, awkward to use or less suitable for rain than expected after just a few weeks.

When it comes to bags and backpacks, these are the three main pitfalls to watch out for:

  1. The stated capacity does not tell the whole story. A bag of, for example, 20 litres may hold less than expected because of thick padding or a lack of practical compartments.
  2. Water-repellent is not the same as waterproof. A water-repellent backpack may help fend off light rain, but it does not automatically protect you during prolonged rainfall.
  3. Lots of compartments can also be impractical. Check whether the compartments are large enough for your phone, keys, water bottle or laptop. A long product description is no substitute for clear measurements.

Which specifications should you check?

1. Capacity, dimensions and intended use

Start by considering how you will use it. A small crossbody bag or bum bag is suitable for your phone, wallet and keys. For sportswear, a drawstring gym bag or swim bag is often a better choice. A travel backpack needs more space and a sturdy internal layout.

As well as checking the number of litres, look at the external dimensions. This is important for:

  • fitting into school lockers or bicycle panniers;
  • storing it under an aeroplane seat;
  • having a laptop compartment for a 13, 14 or 15.6-inch laptop;
  • allowing enough room for sportswear or a towel.

An expandable backpack can be useful for commuting and a weekend trip. However, pay attention to its size when the extra compartment is open. A backpack that looks compact when empty may be less comfortable to carry when fully packed.

2. Fastenings, compartments and access

A drawstring is quick to open and works well for a lightweight drawstring backpack. For valuables, a separate zipped pocket is more practical. In a laptop backpack, a padded laptop compartment and a stable internal layout are important.

Also check whether:

  • the main opening is wide enough;
  • the zipped pocket is positioned against your back or on the inside;
  • small accessories will not disappear to the bottom;
  • the shoulder straps are adjustable;
  • the bag keeps its shape when empty and when full.

A sports bag with one large compartment is simple to use, but may be less organised. Multiple compartments are useful as long as they are sensibly positioned.

3. Material and protection from rain

Nylon and polyester are often used for lightweight bags. Their properties vary from product to product. Look for specific details about the material, finish and care. A coating may help repel dirt or splashes, but always check the product information before using the bag in heavy rain.

Also pay attention to the seams, zips and base. Water can still get in through these areas. For a water-repellent backpack, a rain cover is a practical addition if you cycle every day.

Use this quick checklist to compare different bags and backpacks fairly:

  • Measure your laptop, water bottle or tablet rather than relying solely on the stated screen size.
  • Check both the capacity and the external dimensions.
  • Make sure the shoulder straps are adjustable and wide enough for the way you carry the bag.
  • Find out whether the bag is described as water-repellent, splashproof or waterproof.
  • Check the care instructions. Some materials must not be machine-washed.
  • Check the returns policy, delivery time and product information for the Dutch market.
  • For hand luggage, always follow the rules of the specific airline.

Frequently asked questions about bags and backpacks

Which bag is suitable for commuting?

That depends on what you carry. A crossbody bag or bum bag is enough for small personal items. If you carry a laptop, lunch and accessories, you may be better off choosing a laptop backpack with a separate laptop compartment and multiple sections.

How long does a backpack typically last?

Its lifespan depends on the material, load, seams, zips and care. A bag that is filled heavily every day will generally wear out faster than one intended for light use. Avoid overloading it, clean the surface according to the instructions and regularly check the shoulder straps and zips.

Does a larger or expandable backpack cost more to use?

Not necessarily. The main ongoing costs are usually maintenance, accessories such as a rain cover and replacement when parts wear out. An expandable backpack can be practical because you can use one bag for different situations, but check whether you genuinely need the extra capacity.
