Choosing a backpack without making the wrong purchase: a practical guide for school, work, travel and outdoor use

A backpack may seem simple to choose, but marketing terms do not always tell the whole story. A model with “large capacity” can become awkward once it is full. “Waterproof” may in practice only mean that the fabric repels water, while zips and seams remain vulnerable. And a laptop compartment for 15.6 inches will not automatically fit every laptop of that size.

For students, school pupils, employees, commuters, travellers and sports enthusiasts, three pitfalls are particularly important:

  • Paying too little attention to the layout: one large compartment makes belongings difficult to reach and may not provide enough protection for a laptop.
  • Confusing water resistance with waterproofing: a water-repellent backpack is suitable for light rain, but not necessarily for prolonged downpours.
  • Overestimating the size: a large backpack offers more space, but can become heavy and uncomfortable when you fill it completely every day.

By checking the dimensions, material and intended use properly, you can avoid paying for features that do not suit your routine.

Which specifications should you check?

1. Size and laptop compatibility

A 15.6-inch laptop backpack is a logical choice for many students and employees. In addition to the stated screen size, check your laptop’s actual dimensions. Casing sizes vary between brands and models. Measure the laptop’s length, width and thickness, then compare these measurements with the laptop compartment on the product page.

For school or work, a separate laptop compartment, several smaller compartments and a sturdy base are also useful. If you only carry clothing, lunch and accessories, a lightweight backpack without an extensive tech layout may be perfectly adequate.

2. Water-repellent or waterproof?

These terms have different practical implications:

  • A water-repellent backpack helps protect against splashes and short showers.
  • A waterproof backpack should, according to the product description, offer greater protection against water, but the precise level of protection depends on the seams, zips and fastenings.
  • A flap, roll-top closure or drawstring can partly shield the opening, but does not guarantee that the contents will stay dry during prolonged rain.

If you cycle with a laptop every day, look at the closure and the position of the laptop compartment. A rain cover can provide useful additional protection. Also check whether the manufacturer states a specific waterproofing standard or IP rating. If this information is not provided, do not assume the backpack offers complete protection.

3. Carrying comfort and capacity

A large backpack is useful for weekend clothes, books or sports equipment, but capacity is not the only criterion. Pay attention to adjustable shoulder straps, the back panel, weight distribution and the way the bag opens.

A work backpack or business backpack often benefits from a wide opening and a well-organised interior. A school backpack should mainly be able to carry books, a laptop and a drinks bottle in an orderly way. For travel, an expandable model may be more useful than a fixed-size bag. For hiking, a stable fit is important, while a drawstring sports bag is mainly suitable for lightweight clothing, shoes or a towel.

Caring for your backpack and helping to extend its lifespan

Its lifespan depends on the material, the load and how it is used. A few simple habits can help reduce wear and tear:

  • Keep heavy items close to the back panel.
  • Do not put excessive strain on zips and seams.
  • Brush off mud and dirt promptly with a soft brush.
  • Only wash a backpack according to the manufacturer’s instructions.
  • Allow wet fabric to air-dry and avoid direct sources of heat.
  • Check the shoulder straps, buckles and zips regularly.

Similar considerations apply to footwear. According to the product information, the Salomon Genesis has an upper made from reinforced mesh and synthetic material. According to the product description, the WARRIOR Matterhorn uses suede, Cordura and a rubber sole. These materials require different care from fully synthetic hiking shoes. Measure your foot and use the size chart before ordering trail-running shoes or hiking shoes.

Frequently asked questions about backpacks

Which backpack is suitable for a 15.6-inch laptop?

Choose a model that explicitly states 15.6 inches and compare this with your laptop’s dimensions. Also look at the protection around the compartment, the closure and the position of the laptop inside the bag.

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

A water-repellent backpack may be suitable for short showers. In prolonged rain, additional protection, such as a rain cover, is advisable. Check whether the manufacturer provides information about the seams, zips or a waterproofing standard.

How large should a backpack for work or a short trip be?

That depends on what you need to carry. An everyday model is often enough for a laptop, lunch and accessories. For clothing and travel essentials, an expandable backpack with a stated capacity of 25L to 35L may be more practical. Only choose a larger capacity if you will actually use it.
