How to choose a backpack without regret: find the right bag for walking, travel and everyday use

A backpack seems easy to choose, until you start using it every day. That’s when you notice whether the shoulder straps dig in, the compartments are awkward or your belongings stay dry during a British downpour. A low price also says little about carrying comfort, and a high capacity doesn’t automatically mean the bag is easy to pack.

When buying a backpack, look out for these three common pitfalls:

  • Focusing too much on capacity: a 40- or 45-litre backpack could be unnecessarily large for commuting or a day walk.
  • Unclear claims about water resistance: ‘water-repellent’, ‘anti-splash’ and ‘waterproof’ don’t mean the same thing. Check whether the zips and seams offer protection too.
  • A universal fit without proper adjustment: a unisex backpack may suit different users, but the back length, hip belt and shoulder straps still need to fit your body.

Which specifications matter?

1. Capacity to suit your activity

For a backpack for school and everyday use, around 18 to 25 litres is often practical. The PUMA Academy, for example, has a capacity of around 24 litres and measures 45 × 30 × 18 cm. That gives you room for documents, clothes and everyday accessories without being the size of a trekking backpack.

A compact 10- to 15-litre walking backpack is suitable for a short walk, cycle ride or visit to town. For a weekend with camping gear, a 40-litre or 45-litre backpack is a better choice. Bear in mind that a larger bag can be easier to overpack and make too heavy.

2. Carrying comfort and fit

Check whether the bag has adjustable shoulder straps, a chest strap and, if needed, a hip belt. An adjustable back length matters more on a trekking backpack than on a simple daypack. According to the product specifications, the 40-litre PELLIOT trekking backpack is available for torso lengths of 38–46 cm or 45–53 cm. Its hip belt is designed to fit different waist measurements.

A frame, padded hip belt and ventilation can help distribute the load more evenly. That doesn’t guarantee a comfortable fit for everyone: fit and how you pack the bag still matter. Place heavy items close to your back and adjust the hip belt before tightening the shoulder straps.

3. Material and rain protection

A water-repellent backpack is useful in light rain, but check exactly what the manufacturer claims. According to the product description, the Beneunder LC183 is made from nylon with a protective coating that is said to resist wind, rain and stains. This is a product claim from the brand, so treat it as a practical feature of this model rather than a guarantee that your belongings will stay dry in prolonged rain.

Also consider how you’ll use the bag. A separate rain cover, a waterproof case for electronics and carefully fastened zips offer extra protection. A foldable backpack is handy as a spare when travelling, but often offers less support than a sturdy outdoor backpack.

Frequently asked questions about backpacks

What capacity do I need for walking?

A 10- to 20-litre walking backpack is often enough for a short walk. For a day trip with extra clothes, food and a raincoat, 20 to 30 litres may be more practical. A 40- or 45-litre backpack is mainly intended for multi-day walks, trekking or camping.

How can I make a backpack more comfortable?

First, adjust the back length if possible. Then place heavy items close to your back, fasten the hip belt firmly but comfortably, and adjust the shoulder straps evenly. Use a chest strap to keep the shoulder straps in place. As you walk, check that the bag isn’t pulling to one side.

How long does a backpack last?

A backpack’s lifespan depends on its material, load, care and conditions of use. Check the zips, seams and shoulder straps regularly. A bag that’s consistently overloaded will wear out more quickly. Clean it according to the instructions; several models above are designed to be cleaned with a damp cloth or by hand and must not be machine-washed.
