Buying a backpack: how to choose a practical bag for school, work and travel

Buying a backpack sounds simple, until you find yourself dealing with a laptop compartment that is too small, poor-quality zips or limited comfort every day. Marketing copy often mentions “large capacity” or “water-resistant fabric”, but these terms do not always tell you enough about how the backpack performs in daily use.

Pay particular attention to these common pitfalls:

  • A laptop compartment that does not fit your laptop: a bag for a 15.6-inch laptop may be a tight fit in practice because of the device’s shape or thickness.
  • Confusing water-resistant with waterproof: water-resistant fabric helps protect against light rain, but does not guarantee protection during prolonged or heavy rainfall.
  • Lots of compartments but little usable space: several small compartments may seem convenient, while books, clothing or a lunch box do not fit properly in the main compartment.
  • Comfort that disappoints over time: adjustable shoulder straps are useful, but also look for a padded back and suitable bag dimensions.

Which specifications should you check?

1. Size and laptop compatibility

Do not just look at the number of inches in the product name. Also check the internal dimensions of the laptop compartment and compare them with your laptop. A 15.6-inch laptop can vary in width, height and thickness depending on the brand and model.

For school or work, a laptop backpack with a separate padded compartment is practical. If you mainly carry books, sportswear or accessories, a spacious backpack with a large main compartment is often more important than lots of small pockets.

When choosing a 15.6-inch backpack, also check the overall external dimensions. A bag may be suitable for a laptop but still be awkwardly large for cycling or busy public transport.

2. Material and rain protection

Materials such as polyester, canvas and 900D fabric have different properties. 900D tear-resistant fabric refers to a strong weave designed, according to the product information, to resist tearing. This does not automatically indicate how long the bag will last with intensive use.

With a water-resistant backpack, remember the difference between water-resistant and waterproof:

  • Water-resistant: suitable for light rain or short showers.
  • Waterproof: designed to keep water out for much longer, often with additional features such as covered seams and waterproof zips.
  • No stated protection level: assume limited rain protection and use a rain cover if necessary.

According to the product description, the NINETYGO backpack has water-resistance level 4. However, it also states that the bag is not fully waterproof and should not be exposed to heavy rain for extended periods.

3. Carrying comfort and organisation

For a backpack for work, school or travel, adjustable straps are important. A padded back, a stable handle and wide shoulder straps can make carrying more comfortable. Also check that the straps offer enough adjustment options for your height.

A lightweight backpack is useful for everyday use, but low weight should not come at the expense of a solid basic construction. For sporty users, a sporty backpack with a simple main compartment may work better than a business bag with lots of rigid components.

Frequently asked questions about buying a backpack

How big should a school backpack be?

That depends on the books, laptop and accessories you carry every day. A spacious main compartment is useful for a school backpack, while a separate laptop compartment provides extra protection and keeps everything organised. Always compare the internal dimensions with your laptop and planner, especially when looking for a 15.6-inch backpack.

How long does a backpack last on average?

Its lifespan depends on the load, materials, zips, seams and maintenance. A backpack that is filled heavily every day will wear out faster than a bag used for light commuting. Do not fill the bag beyond the recommended capacity, and clean canvas or coated fabric according to the care instructions.

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

A water-resistant backpack can be practical for short journeys in light rain. During prolonged rain, a rain cover or a fully waterproof cycling bag is a safer choice for protecting your laptop and clothing. Always check whether the manufacturer only states water resistance or also provides a specific waterproof rating.
