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

Buying a backpack seems simple until you have to choose between a laptop backpack, school backpack, sports backpack or spacious travel bag. An attractive photo and a low price reveal little about carrying comfort, organisation and suitability for everyday use. With the right checks, you can avoid finding that your bag is awkward to use after just a few weeks.

Common pitfalls when buying a backpack

1. A large capacity without practical organisation

A spacious backpack is not automatically practical. A large main compartment without smaller sections can leave keys, chargers and cards lost at the bottom. So check whether the bag has a front pocket, side pockets or a separate compartment for a laptop or tablet.

Also pay attention to the difference between capacity and dimensions. A bag may offer plenty of litres, but still be difficult to pack because of a narrow opening. For school and work, a well-organised layout is often more important than simply having a high capacity.

2. Confusing “water-resistant” with completely waterproof

A water-resistant backpack can help repel light rain, but that does not automatically mean that the seams, zips and interior will remain protected during heavy rain. Check the exact product description and look for terms such as water-repellent or waterproof.

When a brand states that a product offers a certain level of protection, you should treat this as a claim from the brand’s product description. For valuable electronics, consider using a separate cover or waterproof inner bag.

3. Adjustable straps that do not fit properly

Adjustable shoulder straps are useful, but carrying comfort also depends on their width, padding, the back panel and how the bag is packed. A narrow bag filled with heavy books can feel very different from an evenly packed backpack. So check:

  • whether the shoulder straps are adjustable and wide enough;
  • whether the back panel is padded;
  • whether the bag is no larger than you need for everyday use;
  • whether the weight can be distributed across several compartments.

Important specifications to check

Capacity, size and intended use

For a school backpack or work backpack, a capacity of around 18 to 25 litres is often practical for books, clothing and everyday accessories. A compact bag is usually better suited to commuting with minimal luggage. For sport or a short trip, a larger bag may be more convenient.

A large travel bag requires different features. Look for a wide opening, sturdy handles and the option to store the bag compactly. According to the product description, the Beneunder LC167 has a standard capacity of 75 litres, which can be expanded to 140 litres. The bag weighs approximately 398 grams. Its stated maximum load is 50 kg; this is a manufacturer’s product specification, not a recommendation to load the bag to that weight as standard.

Laptop compartment and protection

If you are looking for a laptop backpack, do not only check the screen size in inches. Make sure that the device compartment is properly padded, that the device stays securely in place and that the zip does not sit directly against the laptop. A product designed for a particular device size does not automatically provide the same protection as a hard laptop case.

The PUMA Academy Backpack states a maximum compatible device size of 18.7 inches. It also has two main compartments, a front pocket, two side pockets and an elasticated padded inner pocket. Always check the dimensions of your own laptop or tablet before buying.

Material, seams and care

Polyester and synthetic fabrics are often used for a black backpack or unisex backpack. However, the material name alone does not tell you how the bag will perform in everyday use. Look at the construction, reinforced seams, zips and care instructions.

For the Beneunder LC167, the product information states that it is made from an abrasion-resistant, oil- and stain-resistant fabric with water-repellent properties and reinforced stitching. The care instructions recommend cleaning with a damp cloth and allowing the bag to air-dry. Machine washing, harsh chemicals and prolonged exposure to direct sunlight are not recommended.

Frequently asked questions about buying a backpack

What capacity do I need for a work backpack?

Around 18 to 25 litres is often enough for a laptop, lunch, charger and a few personal items. If you carry sportswear or extra shoes, choose a more spacious backpack. Do not only check the capacity, but also the width of the laptop compartment and the opening of the main compartment.

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

That depends on the exact level of protection. “Water-resistant” or “water-repellent” usually indicates protection against light rain, but it is not the same as being waterproof. Give electronics extra protection and check whether the product information mentions zips, seams and prolonged exposure to rain.

How long does a backpack last?

Its lifespan depends on the material, seams, zips, carrying weight and frequency of use. A bag that is heavily loaded every day will wear out faster than a backpack used occasionally. Follow the care instructions, do not overload the bag and choose a model with enough space for your usual belongings.
