A 15.6-inch laptop backpack needs to do more than simply carry a laptop. Students often take books and a charger with them, commuters have to deal with rain and crowded trains, while travellers want to carry extra clothing and documents. Yet many models look much the same at first glance.
That is why you should pay particular attention to three common purchasing pitfalls:
Confusing “waterproof” with water-repellent
A product title may use terms such as waterproof or water resistant, but that does not automatically mean the bag can withstand heavy rain for extended periods. Check whether the material, seams and zips are actually described as water-resistant. A water-repellent backpack is generally suitable for light rain, but a separate rain cover may be a sensible choice if you cycle every day.
Looking only at the screen size
A laptop with a 15.6-inch screen does not always have the same external dimensions. A thick work laptop, gaming laptop or laptop with wide screen bezels may be larger than the laptop compartment. Measure the laptop itself and compare its dimensions with those of the stated compartment.
Confusing plenty of capacity with good carrying comfort
A spacious laptop backpack can be useful, but a full bag quickly becomes heavy. Look for padded shoulder straps, a firm back panel and, where appropriate, a chest strap. A larger capacity, such as that offered by a 25-litre backpack, is particularly useful when you regularly make use of the extra space.
Look for a separate, well-fitting laptop compartment. This helps prevent the laptop from moving around loose among books, cables and other belongings. Also check:
A laptop backpack for work and school often benefits more from a well-fitting compartment and an organised layout than from an exceptionally large main compartment.
Polyester and canvas are commonly used for laptop backpacks. The product description should make it clear whether the material is described as water-repellent, water-resistant or waterproof. These terms are not automatically interchangeable.
Pay attention to the fastening as well. A roll-top or flip-top design can partially shield the opening, but the level of protection also depends on the construction and seams. When cycling in changeable weather, do not carry electronic devices without additional protection unless the manufacturer provides clear information to the contrary.
Think in advance about what you need to carry every day:
An expandable backpack can stay compact on working days and offer extra space when travelling. With a model that expands from 25 to 30 or 35 litres, however, you should allow for additional weight when using the expanded capacity.
A backpack with a USB port can be practical for connecting a power bank. The port does not charge devices by itself: you need a suitable power bank and cable. Also check whether the power bank fits in a separate compartment.
RFID protection is a specific feature that is not included in every business backpack. According to HP’s product information, the HP Travel model has a concealed RFID-blocking compartment. This is an HP product specification; the feature should not be presented as a guarantee against every form of data theft.
The following selection is based on stated features such as laptop size, capacity, fastening and expandability. Before ordering, always check the current dimensions, colour and product specifications on the product page.
Why it suits this profile: This model is designed for everyday use at school, work and around town. The flip-top fastening and stated 15.6-inch compatibility make it a good choice if you want a straightforward laptop backpack without needing a full travel-size design straight away.
The product title states that it has a water-resistant design and accommodates a 15.6-inch laptop. However, check your laptop’s exact dimensions before ordering.
Suitable for a 15.6-inch laptop; flip-top and drawstring fastening; described as a model for school, work and travel.
Why it suits this profile: This business backpack is well suited to commuters and travellers who value a fixed layout, expandable capacity and additional organisational features.
The capacity is specified as 25 litres and expandable to 30 litres. This lets you adapt the amount you carry for commuting or a short trip, rather than relying solely on a large main compartment.
15.6-inch laptop compartment; capacity of 25 to 30 litres; chest strap; concealed RFID-blocking compartment; lockable zips according to the product information.
Why it suits this profile: This expandable design is intended for travellers, weekend use and commuters who sometimes need to carry extra clothing or documents.
The stated capacity increases from 25 to 35 litres. This makes the difference between everyday luggage and travel luggage clearer, but bear in mind that extra capacity can also mean extra carrying weight.
Expandable capacity of 25 to 35 litres; described as waterproof; designed as a business and travel backpack for a 15.6-inch laptop.
For cyclists and urban commuters, a roll-top laptop backpack can be practical because the top closes flexibly. The Water Repellent Roll Top Laptop Backpack is described as a water-repellent model for work, cycling and urban travel. If you prefer a more classic look, consider the 15.6-inch vintage canvas backpack. Canvas can suit a casual style, but here too, check the fastening and protection from rain.
A model with an external USB charging port, such as the Expandable Business Travel Backpack, is particularly useful if you want to use a power bank while on the move. For a business backpack, a trolley strap, document compartment and lockable compartments are also useful features to check.
We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
No, not automatically. The inch measurement refers to the screen diagonal, not the laptop’s overall dimensions. Measure the laptop and compare its width, height and thickness with those of the laptop compartment.
Its lifespan depends on the load, materials, zips and frequency of use. A bag that is constantly overloaded will wear out more quickly. Distribute the weight evenly, place heavy items close to your back and only use the expansion zip when necessary.
A water-repellent backpack may be sufficient for light rain, but it does not offer the same protection as full waterproofing. In prolonged or heavy rain, a rain cover is advisable. Also keep your laptop in its own compartment and avoid leaving zips open while cycling.
