Choosing a lightweight backpack: practical buying tips for work, travel and walking

A lightweight backpack may seem like a simple choice at first. But attractive product photos and terms such as “ultralight”, “waterproof” or “large capacity” can give you the wrong impression. A bag may be light but offer too little support. Or it may have lots of pockets, leaving hardly any room for a jacket, laptop or lunch.

There are three common pitfalls to watch out for:

  • A lightweight bag isn’t automatically comfortable. Thin shoulder straps, limited back ventilation or a poor fit that’s difficult to adjust can quickly become uncomfortable with daily use.
  • Water-repellent doesn’t mean waterproof. Water-repellent fabric helps protect against light rain or splashes. It doesn’t mean the contents will stay dry during a prolonged downpour.
  • The stated capacity doesn’t tell you everything. Zip pockets, laptop sleeves and reinforced panels take up space too. Check the external dimensions, layout and size of the laptop compartment.

Which features should you check?

1. Weight, capacity and external dimensions

Don’t just look at the weight: consider it alongside the usable capacity. A roomy backpack for commuting has different requirements from a small foldable backpack for a day walk.

Check the following:

  • Is the weight given in kilograms or grams?
  • What is the bag’s capacity in litres in its standard configuration?
  • Is the capacity expandable?
  • Will the external dimensions fit your mode of transport, locker or hand luggage allowance?

For example, the Kono cabin backpack has a stated weight of 0.5 kg, a capacity of around 24 litres and external dimensions of 40 × 30 × 20 cm. Always check your airline’s current baggage rules before travelling. Dimensions can vary between airlines and fare types.

It’s worth checking both configurations for an expandable model. According to the product specifications, the Beneunder LC183 has a capacity of 10 litres in its standard configuration and 13 litres when expanded. This is handy if you’re travelling light on the way out but need extra space during your trip.

2. Protection for your laptop and other belongings

If you’re looking for a 15.6-inch laptop backpack, look beyond the product name. Check whether a padded laptop compartment is specifically mentioned and whether its internal dimensions will fit your device. A 15.6-inch laptop’s dimensions can vary by make and model.

A separate laptop compartment helps keep your computer apart from your other belongings. For everyday commuting, a document pocket, cable organiser and sturdy base are also useful. A USB port or cable pass-through is mainly a convenience feature, so check whether a power bank is included. The Kono backpack is listed with a cable pass-through, but the product information doesn’t state that a power bank is included.

3. Material and rain protection

A backpack should only be described as waterproof when this is clearly supported by the product specifications. Terms such as “water-repellent”, “anti-splash” and “water-resistant” usually mean protection against splashes or light rain, not prolonged immersion.

The Beneunder LC183 is described as being made from nylon with a protective fabric that helps resist wind, rain and stains. The product description presents this as a protective feature; in heavy rain, use a rain cover or give your electronics extra protection.

The Beneunder LC359 is described as featuring outdoor fabric and high-polymer PC panels as part of its StrongShield protection system. According to the brand, this is designed to protect against impact and support heavier loads. It doesn’t guarantee that the backpack will remain undamaged in every situation. Overloading it can also affect its shape and comfort.

Frequently asked questions about lightweight backpacks

Is a lightweight backpack suitable for everyday commuting?

Yes, as long as its capacity, straps and protection suit what you need to carry. For a laptop, documents and lunch, a separate laptop compartment, multiple compartments and padded shoulder straps are useful. A 10-litre model may be enough for a compact work kit; you’ll need more capacity for extra clothes or sports kit.

How long does a lightweight backpack last?

Its lifespan depends on the material, zips, seams, load and how well you look after it. Avoid regularly exceeding the stated capacity, and keep the bag away from sharp or abrasive objects for prolonged periods. Clean it according to the product instructions, usually with a damp cloth. Leave a wet backpack to air-dry, and don’t store it while it’s damp for long periods.

Do I need a rain cover for a lightweight backpack?

Water-repellent material may be enough in light rain, but this depends on the product and how long you’re out in it. If you’re carrying a laptop, camera or documents, extra protection is a good idea. A rain cover or waterproof inner bag means you don’t have to rely solely on a marketing term such as “waterproof” or “water-resistant”.
