A backpack needs to do more in daily life than just offer storage space. School pupils carry books and A4 folders, students need room for a laptop and charger, professionals look for organised compartments, and travellers need dimensions that fit carry-on luggage. At the same time, many models boast terms like "waterproof", "ergonomic" or "large capacity" without clearly explaining their practical limitations.
That's why the Joybuy Product Recommendation Officer has filtered relevant product data to show what buyers in the UK should look out for in 2026.
A water-repellent or splash-proof material can withstand a short shower. However, this does not automatically mean the entire backpack will stay dry in heavy rain or prolonged contact with water. Seams, zips and openings are potential entry points.
So look for specific ratings such as IPX4, "splash-proof" or "water-repellent polyester". A backpack advertised as waterproof should only be considered as such if the manufacturer clearly describes the protection level or construction.
A backpack with a high litre capacity can be impractical if your laptop, books, water bottle and small items all end up in one main compartment. For school and work, separate compartments are often more important than the largest possible volume.
Check whether there is a padded laptop compartment, internal pockets or easily accessible outer pockets. With a roll-top model, the volume can also change depending on how high you roll the closure.
The description "15.6-inch laptop backpack" doesn't always accurately describe the maximum device size that will fit. What matters are the internal dimensions of the laptop compartment and the shape of your device. A 15.6-inch notebook can vary in width and depth depending on its design.
So compare your laptop's dimensions with the manufacturer's specifications. A laptop compartment designed for 13.3 inches won't automatically fit larger devices, even if the outer backpack looks roomy enough.
For a daypack, 10 to 20 litres is often sufficient depending on what you need to carry. A school backpack or business backpack with books, a change of clothes and tech may require 20 to 30 litres. For travel, it's not just the volume that matters, but also the external dimensions.
A 24-litre backpack, for example, can hold A4 folders, while a 10-litre model is better suited to a tablet, notebook and personal items. It's a good idea to realistically think about what you'll be carrying before you order.
Padded shoulder straps and a padded back panel can improve comfort during longer use. For heavier loads, a chest strap is helpful because it can stabilise the shoulder straps. However, a good fit doesn't replace sensible weight distribution.
The backpack's own weight also matters: the Xiaomi Casual Daypack weighs 165 grams according to the product information, while the Eastpak Padded Pak'r with 24 litres is listed at 400 grams. On daily commutes by bus, train or bike, every extra gram can make a difference.
Polyester and nylon are common materials for everyday, school and travel backpacks. More important than a general material name are the specific construction, padding and protection of the openings. Reinforced seams, sturdy zips and a durable base are useful features for frequent use.
Also pay attention to the care instructions. Several of the models mentioned here should not be machine washed, soaked or bleached, according to the product description. Cleaning with a damp cloth or a soft brush may be recommended depending on the model.
Why it fits: This compact everyday backpack is suitable for A4 formats, school and leisure time according to the product information. 24 litres offer space for typical daily essentials.
The specifications clearly state the volume, dimensions and weight. This makes it easier to compare the backpack with your actual needs, rather than just relying on marketing claims.
Padded back panel, padded shoulder straps, front zip pocket and 400 grams weight.
Why it fits: This backpack combines laptop storage, multiple compartments and an expandable design for commutes and business trips.
The product name explicitly states suitability for 15.6-inch laptops. However, you should still check your device's specific dimensions before buying.
Expandable storage, multiple compartments and an externally mentioned USB charging port. The charging port does not replace a power bank.
Why it fits: The stated dimensions are designed for under-seat storage on Ryanair. Airline policies can change, so you should check them again before you travel.
The external dimensions of 40 x 20 x 25 cm and the weight of 500 grams are clearly stated. This makes it easier to check against baggage regulations.
20 litres volume, trolley strap, chest strap, compression straps and multiple compartments for travel documents and tech.
Why it fits: This model is aimed at professionals, students, cyclists and anyone who needs to switch flexibly between work, study and leisure gear.
The flexible capacity is stated as 25 to 30 litres. In addition, the laptop compartment, internal pockets and two side pockets are clearly described.

In our category you'll find a regularly updated selection for school, work, everyday life, laptop transport and travel. Always check the dimensions, capacity and material information before you buy.
For an especially lightweight model, the Xiaomi Casual Daypack could be of interest: it offers 10 litres of volume according to the product information, weighs 165 grams and can hold notebooks or tablets up to 14 inches. The IPX4 rating describes protection against splashes, not complete immersion.
If you're looking for a classic Eastpak backpack with a larger laptop compartment, you'll find models with 27 litres of volume, 500 grams weight and a compartment for 13.3-inch laptops. For larger devices, you should instead choose a dedicated 15.6-inch laptop backpack.
For light everyday items, 10 to 15 litres can be enough. For school, university or work, 20 to 30 litres is often more practical, especially if you need to carry a laptop, folders, water bottle and clothing together.
Not in every case. For short journeys, a water-repellent or splash-proof backpack may be sufficient. For longer bike rides or heavy rain, welded seams, waterproof zips or an additional rain cover are relevant points to check.
The lifespan depends on the load, materials, seams, zips and care. Avoid overloading, clean the model according to the manufacturer's instructions and let it air dry completely after getting wet. It's not possible to give a general lifespan without specific load and material data.
