Choosing a backpack without regret: practical tips for school, work and travel

A backpack seems like a simple purchase, until you’re carrying a laptop, books or clothes every day. A bag may look spacious in the product photo, but have too few compartments in practice. Terms such as “waterproof”, “ergonomic” and “suitable as hand luggage” aren’t always used consistently either.

So keep an eye out for these common pitfalls:

• Water-repellent isn’t the same as waterproof. A water-repellent backpack can help keep out light rain, but it won’t necessarily protect your belongings during prolonged or heavy rainfall.
• A laptop compartment won’t always fit your device. Check the stated screen size in inches as well as the internal dimensions. A 15.6-inch laptop backpack can vary from one model to another.
• Hand luggage size limits depend on the airline. Check the current requirements before you travel. A bag sold as a Ryanair backpack must still meet the requirements for your ticket and flight.
• More compartments don’t automatically mean a more practical layout. Check whether the main compartment opens wide enough and whether you can easily reach your everyday essentials.

Which specifications matter?

1. Dimensions and capacity

For school or work, height, width and depth matter more than the litre capacity alone. A school backpack of around 20 to 25 litres will often have room for books, lunch and accessories. For a short trip, a travel backpack of around 24 litres may be more convenient if it opens fully, like a small suitcase.

For hand luggage, don’t just measure the bag when it’s empty. Packing it mustn’t make it exceed the permitted dimensions. The Kono model is listed with external dimensions of 40 × 30 × 20 cm, a weight of around 0.5 kg and a capacity of approximately 24 litres. The product description says these dimensions meet the commonly used personal-item requirements for Ryanair. Always check the airline’s current rules yourself before booking.

2. Laptop protection and carrying comfort

Ideally, a laptop compartment should be padded and keep your device from resting directly on the bottom of the bag. Check that the compartment is suitable for your laptop size too. A laptop backpack for your daily commute will also benefit from:

• Adjustable, padded shoulder straps
• A back panel with ventilation or soft padding
• A sturdy handle
• A separate place for your charger, mouse and cables
• A luggage strap if you regularly travel with a suitcase

A backpack with a USB port can be handy on the go, but the port won’t charge your device by itself. These models usually need a power bank. Check whether one is included; the Kono school model explicitly states that the power bank isn’t included.

3. Material and rain protection

Polyester, Oxford fabric and canvas all have different properties. Polyester and Oxford fabric are often used for lightweight, everyday bags. Canvas can give a bag a more casual look, but may need more care. Pay attention to the exact wording:

• Water-repellent: helps protect against splashes and light rain.
• Water-resistant fabric: the fabric may keep moisture out temporarily, but seams and zips can still be weak points.
• Waterproof: usually requires additional construction features, such as sealed seams and protected zips.

If you’re cycling in the rain for a long time, always use an extra protective case for your electronics. Claims about durability or protection are made by the brand or seller, so check the specific material details and care instructions.

Frequently asked questions about backpacks

What capacity is suitable for everyday use?

For school, work and commuting, around 18 to 25 litres is often practical. Choose a larger bag if you need to carry sportswear, lunch and books at the same time. As well as capacity, consider the shape of the main compartment and where your laptop goes.

Is a backpack with a USB port useful?

It can be handy when travelling or during long working days. The USB port usually connects to a power bank inside the bag. Check whether the internal cable is included, and bear in mind that you’ll usually need to buy the power bank separately.

How long does a backpack last?

Its lifespan depends on how heavily it’s used, how often the zips are opened, exposure to moisture and how well it’s maintained. A bag packed heavily every day will wear out faster than one used lightly. Avoid overloading it, clean it according to the instructions and regularly check the seams, base and shoulder straps. This helps you spot when it may need replacing and avoid problems caused by a damaged bag while you’re out and about.
