Choosing a Backpack Without Regrets: A Practical Guide for School, Sport, Hiking and Travel

A backpack may seem like a simple purchase, until you have to carry an ill-fitting bag every day. A school backpack that is too small leaves belongings loose, thin shoulder straps quickly become uncomfortable, and a bag described only as “waterproof” may still let water in during a typical British downpour.

For school pupils, students, cyclists, athletes, hikers and travellers, three common pitfalls are particularly important:

  • Focusing only on capacity: a large backpack offers more space, but can become awkwardly heavy if it lacks good weight distribution or carrying support.
  • Confusing marketing claims with specifications: terms such as “water-repellent”, “durable” and “ultralight” mean little without details about the material, dimensions or weight.
  • Underestimating carrying comfort: adjustable straps are useful, but for longer walks a chest strap, hip belt and ventilation are also important.

Which backpack suits your needs?

First, consider what you usually carry. A sporty backpack for clothing and a water bottle needs different features from a school backpack for books and a laptop. For a short walk, a lightweight backpack is often sufficient, while a trekking backpack for several days needs more support and attachment points.

When comparing backpacks, pay attention to these points:

  • Everyday use and school: around 20 to 25 litres is often practical for books, clothing, accessories and lunch. Multiple compartments help keep smaller items separate.
  • Fitness and swimming: a gym bag with a drawstring or a drawstring backpack is lightweight and easy to access. A separate zipped pocket is useful for keys, your phone or cards.
  • Hiking and cycling: a hiking or cycling backpack should sit securely against your back. Look for a ventilated back panel, adjustable shoulder straps and a chest strap.
  • Travel: a travel backpack should not simply be large. A well-organised layout, sturdy zips and a comfortable carrying system are just as important.
  • Extra luggage: a foldable backpack takes up very little space when not in use. Do check the material and stated load capacity.

Three specifications to check before buying

1. Capacity, dimensions and carrying weight

The capacity in litres gives you an indication of the available space, but it does not tell you how efficiently that space is organised. In practice, a 22-litre bag with a spacious main compartment and a front pocket may be more useful than a larger bag without any structure.

Also check the dimensions. A bag measuring 45 × 30 × 18 cm will fit differently from a compact model measuring 43 × 30 × 14 cm. For school and work, the maximum compatible device size is also relevant. The PUMA Academy Backpack states a maximum compatible device size of 18.7 inches; always check that this matches your laptop or tablet. A backpack with a laptop compartment is only suitable if the compartment actually offers the right size and protection.

2. Carrying comfort and adjustability

Look for padded shoulder straps, a padded back panel and plenty of adjustment options. On a hiking or trekking backpack, a chest strap and hip belt are useful for distributing the load more effectively. Keep heavy items close to the back panel and avoid allowing the bag to hang unnecessarily high or at an angle.

For intensive cycling or trail running, a stable fit is more important than maximum capacity. A compact model of 10 to 20 litres may therefore be more practical than a large backpack that shifts around while you move.

3. Material and protection from rain

Polyester, nylon and coated Oxford fabric are common materials. However, a product name containing “waterproof backpack” is not a complete technical guarantee. Check whether the product information mentions a coating, waterproof zips, taped seams or an included rain cover. Without these details, it is safer to assume protection against light rain rather than long-lasting waterproofing.

Even strong materials require careful use. Sharp objects can damage fabric, while prolonged exposure to sunlight can cause coatings to deteriorate. Always follow the product’s care instructions.

Frequently asked questions about backpacks

What capacity does a backpack for school or work need?

For everyday use, a capacity of around 20 to 25 litres is often a good choice. This provides room for books, lunch, clothing and accessories. Measure your laptop or tablet before buying a model; the stated capacity in litres says nothing about the dimensions of a device compartment.

How do you adjust a backpack for maximum comfort?

Place heavy items close to your back, adjust both shoulder straps evenly and make sure the bag does not hang unnecessarily low. On a hiking backpack, use the chest strap for extra stability. A hip belt can help transfer some of the load from your shoulders to your hips.

How long does a backpack last?

Its lifespan depends on the material, load, weather and maintenance. Overloading, sharp objects and prolonged exposure to moisture will shorten its usable life. Clean the bag according to the product instructions, allow it to dry completely and regularly check the zips, seams and attachment points. This will help you spot in good time when replacement is needed.
