Choosing a backpack: find the right model for walking, travel and everyday use

A backpack seems like a simple purchase – until you carry it every day or load it up for a long walk. That’s when you quickly find out whether the shoulder straps fit well, the storage is laid out practically and the fabric can cope with a British downpour. Marketing terms such as “ultralight”, “waterproof” and “large capacity” don’t always tell the whole story, either.

That’s why the Joybuy Product Recommendation Officer compares the most important features using verifiable product specifications. This helps you avoid a disappointing purchase and choose a backpack that suits the way you’ll use it – from commuting and school to walking, trekking and camping.

Three common pitfalls when buying a backpack

1. A large capacity without good weight distribution

A 30, 45 or 50-litre backpack can carry a lot, but that doesn’t automatically make it comfortable to wear. If you regularly carry a heavy load, look for a chest strap, a hip belt and adjustable shoulder straps. Without these features, most of the weight rests on your shoulders.

A 30-litre backpack is often practical for a day walk. For a multi-day trip, you may need a 45-litre trekking backpack or larger. Don’t choose based on capacity alone: check the dimensions, the backpack’s own weight and how adjustable it is.

2. Confusing “waterproof” with water-resistant

A water-resistant backpack may keep out light rain or splashes, but that doesn’t automatically make it suitable for prolonged rainfall. Check whether a rain cover, sealed seams or a specific waterproof rating is listed. If this information isn’t available, use a separate cover or waterproof storage bag for electronics and clothing.

3. Too few pockets – or pockets that aren’t practical

A single main compartment isn’t ideal for keys, your phone, a water bottle and documents. A backpack with lots of pockets can make it easier to stay organised, but extra zips and compartments also add weight. Think about what you actually carry. For a laptop backpack, a padded laptop compartment is useful; for an outdoor backpack, attachment loops and mesh side pockets are often more practical.

Important specifications to compare

Capacity and dimensions

Use capacity as a guide:

  • 10 to 15 litres: everyday use, short bike rides and gentle walks.
  • 18 to 25 litres: commuting, school, day walks and trail running.
  • 30 litres: clothing, food and accessories for a day outdoors or a city break.
  • 45 to 50 litres: multi-day walks, trekking or bulky camping equipment.
  • 100 litres or more: heavy camping equipment; a wheeled camping bag may be more practical than a backpack.

Bear in mind that an expandable bag won’t have the same capacity in every configuration. According to the product description, the Beneunder LC183 has a capacity of 10 litres in its standard configuration and 13 litres when expanded.

Weight, back panel and fit

A lightweight backpack is useful for cycling, travel and walks where you’re carrying only a few things. If you’re carrying a heavier load, a ventilated back panel, padded shoulder straps and a hip belt matter more than a difference of a few hundred grams.

Check the back length and strap adjustment, too. According to the product specifications, the PELLIOT Trail Running Backpack is available in different size ranges for the torso and waist. This matters if you’re looking for a hiking backpack that needs to stay close to your body during vigorous movement.

Material and protection

Nylon, polyester and Oxford fabric are commonly used for backpacks. Their properties depend on the weave, coating and finish. “Hard-wearing” or “tear-resistant” is a manufacturer’s product claim, so treat it as information from the product description rather than a universal guarantee.

Also check:

  • Whether the zips and buckles feel sturdy.
  • Whether the base has extra protection.
  • Whether you can store wet clothing separately.
  • Whether a rain cover is included.
  • Whether the bag should be cleaned with a damp cloth rather than in a washing machine.

Frequently asked questions about backpacks

What size backpack do you need for a day walk?

A 20 to 30-litre backpack is often enough for a day walk. If you’re taking a rain jacket, lunch, water, an extra layer and a camera, a 30-litre backpack gives you more room. For a walk with just the essentials, 10 to 18 litres may be enough.

How can you make a backpack more water-resistant?

Use a rain cover and keep electronics, documents and spare clothing in waterproof bags. First check whether the backpack is only water-resistant. A coating can wear off over time, so follow the manufacturer’s care instructions and don’t put the bag in the washing machine without checking.

How long does a backpack last?

How long it lasts depends on the load, material, moisture, sunlight and care. Overloading it, carrying sharp objects and storing it while wet for long periods can speed up wear. Clean the bag with a damp cloth, let it dry completely and check the seams, zips and buckles regularly. This will help keep your backpack in good condition for everyday use, travel and outdoor activities.
