A bag that looks lightweight in the product photo can disappoint in everyday use. Your laptop may not fit, the bag may sag when carrying shopping, or “water-repellent” may turn out to mean suitable only for a short shower. If you are looking for a practical backpack and foldable bag, it is therefore worth looking beyond colour, price and marketing terms.
For students, working professionals, cyclists and travellers, three pitfalls are particularly important:
For a compact foldable shoulder bag, a capacity of around 15 to 20 litres is often practical for shopping, commuting or a short outing. A spacious tote bag with expandable capacity is more useful when you do not know in advance how much you will be bringing back.
With an expandable bag, pay attention to the difference between its standard and maximum capacity. The Beneunder LC168, for example, is listed as having 20 litres of standard capacity and 35 litres when expanded. This is useful for travel or shopping, but also check the dimensions of the main compartment and base.
A lightweight backpack or bag is useful when you walk or cycle a lot, or want to take an extra bag in your suitcase. However, the bag’s own weight should be weighed against its capacity and carrying structure.
According to the product information, the Beneunder GP155 weighs approximately 64 grams and can be folded into a storage pouch. The LC168 weighs around 220 grams and, according to its description, can be carried by hand or as a backpack. Models like these are particularly suitable as an extra bag or lightweight everyday carryall. For a laptop and heavy accessories, a more structured model is often the more sensible choice.
A 15.6-inch laptop backpack needs more than just a sufficiently large compartment. Check whether the laptop compartment is separately padded, whether the laptop is protected from knocks against the base, and whether the bag closes securely. A roll-top, flap or drawstring provides different access to the main compartment than a bag with a standard zip.
Product titles may include terms such as “water resistant” or “water repellent”. This does not automatically mean that the bag is fully waterproof. Treat this as an indication from the product description and check the full specifications before using the bag in prolonged rain.

Use this quick checklist when comparing a travel backpack, laptop backpack or foldable bag:
That depends on the load. A lightweight model such as the GP155 is practical for shopping and extra luggage. For a laptop, books and everyday accessories, a structured backpack for work and school generally offers better protection and carrying comfort.
Do not look only at the screen size. Measure the entire laptop, including any protective sleeve, and compare those dimensions with the laptop compartment. A laptop backpack with plenty of pockets can be useful for accessories, but extra compartments sometimes reduce the available main storage space.
Its lifespan depends on the weight carried, how it is used, the seams, zips and how well it is maintained. Avoid overloading it, store a foldable bag somewhere dry and follow the manufacturer’s cleaning instructions. A water-repellent bag will also not automatically remain water-repellent if the fabric is washed intensively or exposed to high heat.
