Choosing a backpack without regret: a practical guide for sport, work and travel

A backpack may seem easy to choose, but small differences can determine whether it’s comfortable to use every day. A lightweight school backpack has different requirements from a swimming bag, gym bag or backpack for walking and travel. So don’t focus only on colour and price: pay particular attention to capacity, fastening, comfort and rain protection.

Common pitfalls when buying a backpack

1. The stated capacity doesn’t tell the whole story

A 10-litre backpack sounds spacious, but how much usable room it has depends on its shape and layout. A narrow main compartment may be less practical than a slightly smaller bag with several compartments. So check:

  • the stated capacity in litres;
  • the dimensions of the main compartment;
  • whether it has a separate front, side or phone pocket;
  • whether it’s suitable for a laptop, clothes, a towel or a lunch box.

For a gym or sports bag with a drawstring, one large open compartment is often enough. For commuting or school, several compartments are more useful.

2. “Waterproof” and “water-resistant” are often confused

A water-resistant backpack can help keep out light rain or splashes, but that doesn’t necessarily mean it’s waterproof for extended periods. Check whether the product description says water-resistant, anti-splash or waterproof. Also look at the zips and seams: water can still get in through them.

According to the product description, the Beneunder LC183’s fabric resists wind, rain and stains. This is a product claim made by the brand, so consider the bag suitable for changeable conditions, but use extra protection for valuables in heavy rain.

3. Lightweight material can come at the expense of comfort

A lightweight backpack is handy when cycling, walking or travelling, but thin shoulder straps can become uncomfortable when the bag is heavily loaded. Look for:

  • adjustable straps;
  • the width and thickness of the straps;
  • a design that keeps the weight close to your back;
  • a clearly stated maximum load, if provided.

A drawstring bag is compact and lightweight, but usually offers less support than a traditional backpack with padded straps.

Important specifications to compare

Capacity and size

Choose a capacity to suit how you’ll use the bag each day:

  • Small backpack of around 4 to 6 litres: suitable for a phone, purse, keys and a few small items.
  • Backpack of around 10 litres: practical for commuting, school essentials, lunch and light clothing.
  • Expandable backpack: handy when the amount you need to carry varies from day to day.
  • Drawstring sports bag: suitable for sportswear, shoes or swimming gear, as long as you don’t need sturdy protection or lots of compartments.

Always check the dimensions in centimetres or inches and compare them with your height and the items you want to carry.

Material and care

Nylon and synthetic fabrics are often lightweight and easy to wipe clean, making them suitable for everyday backpacks. A product description may also mention a specific water-resistant treatment. Follow the care instructions: for several models, wiping with a damp cloth and leaving to air-dry is recommended. Machine washing can damage the coating, shape or zips.

Fastening and compartments

A drawstring closes quickly and keeps the bag compact. A zipped pocket at the back is useful for keys, cards or a phone. For travel and commuting, an expandable backpack with several compartments is usually easier to organise. Check that the zips run smoothly and the pockets are large enough for your belongings.

Which backpack is right for you?

For a gym bag or swimming bag, a drawstring style is often practical: it’s quick to open and takes up little space. If you’re carrying wet swimwear, it’s best to put it in a separate waterproof bag; a water-resistant outer fabric doesn’t automatically prevent leaks.

For school, university or the office, a backpack with zipped pockets and enough capacity is more useful. Check in advance that there’s room for documents or a laptop. For walking and short trips, adjustable straps, a lightweight design and an expandable main compartment are useful. A foldable backpack can also serve as an extra bag for shopping or a day out.

Frequently asked questions about backpacks

How do I clean a backpack?

Always follow the manufacturer’s care advice. For synthetic models, wiping with a damp cloth is often suitable. Then leave the bag to air-dry completely and avoid prolonged exposure to direct heat. Don’t machine-wash a backpack unless this is expressly permitted.

How long does a lightweight backpack last?

Its lifespan depends on how heavily and often it’s used, and how well it’s cared for. A lightweight backpack can last a long time with everyday use and a normal load, but overloading puts extra strain on the seams, zips and straps. Check the drawstrings, buckles and stitching regularly, and avoid putting sharp objects in the main compartment.

Is a water-resistant backpack suitable for cycling in the rain?

A water-resistant backpack can be practical in light rain. In prolonged or heavy rain, it’s still wise to keep electronics and documents in a separate waterproof cover. Pay particular attention to the zips, seams and base of the bag, as these parts may not offer the same protection as the outer fabric.
