Buying a backpack seems straightforward until you start dealing with a laptop compartment that is too small, an uncomfortable carrying system or a bag that lets in water during the first shower. Marketing terms such as “waterproof”, “ergonomic” and “cabin-bag size” only mean something when you check the specifications behind them.
For school pupils, students, commuters, travellers and outdoor enthusiasts, three pitfalls are particularly important:
Do not just look at the number of litres. Consider the shape of the bag and its layout too. For everyday use, a document compartment, laptop compartment and smaller zipped pockets are often more practical than one large compartment.
A laptop backpack for a 15.6-inch laptop should not only state the maximum screen size. Also check whether there is enough room for the laptop casing, charger and accessories. A bag that can carry a 15.6-inch laptop backpack is not automatically suitable for heavy schoolbooks or clothing.
For air travel, centimetres are more important than an approximate capacity. A Ryanair bag or other compact cabin bag must comply with the conditions for an under-seat bag or luggage-compartment bag. Always check the airline’s current rules before departure; these may vary depending on the ticket type.
A lightweight backpack reduces the weight you carry around every day. However, low weight alone is not enough. Also look for:
A backpack with lots of compartments can be convenient, but extra zips, attachment loops and sturdy panels can sometimes increase the weight. Choose features that suit the way you intend to use it.
Oxford fabric and recycled synthetic materials are often used for school and travel backpacks. Check what the product description actually states. “Water-repellent” generally means that light rain is kept out temporarily; it is not a guarantee against prolonged rainfall.
A water-repellent backpack with a rain cover provides an additional layer of protection in wet weather. For cycling to and from work, covered zips and a well-sealed laptop compartment are useful. For walking, a backpack with a hydration bladder may be more practical. Check the stated compatibility carefully: a bag designed for a 2-litre water bladder does not always include one.
A backpack with a USB port usually contains only the port and an internal cable. You need to insert the power bank yourself. The USB connection therefore does not replace a charger and says nothing about charging speed.

A medium-sized backpack may be sufficient for a laptop, documents and everyday accessories. School pupils who also carry books, lunch and sportswear will generally need more space. As well as the litre capacity, check the dimensions of the main compartment and the position of the laptop compartment.
That depends on how long and how heavily it rains. Water-repellent fabric can keep out light rain temporarily, but it does not automatically protect against cycling through a shower for an extended period. A rain cover or waterproof inner sleeve can provide additional protection. Also check whether the zips and seams are covered.
No. Permitted dimensions and weight vary by airline and sometimes by ticket. Measure a cabin bag including any protruding parts and check the current conditions before departure. A model with dimensions mentioned in the product description for a particular airline is not a substitute for checking the requirements yourself.
