How to choose a backpack without regretting it: check these features and use cases

A backpack may seem easy to choose, until you start using it every day. Your laptop almost fits, the shoulder straps dig into your shoulders or a brief shower soaks through the fabric. For school pupils, students, laptop users, travellers and outdoor enthusiasts, capacity, carrying comfort and protection from moisture are especially important.

Watch out for marketing claims, too. Lots of pockets don’t automatically mean a practical layout. A USB port only works with your own power bank, and “water-repellent” doesn’t mean fully waterproof. Use the tips below to compare school backpacks, laptop backpacks, travel backpacks and large backpacks based on the features that matter in practice.

Three common backpack pitfalls

1. A stated laptop size without checking the measurements

A backpack labelled “15.6 inches” won’t necessarily fit every laptop of that size. The laptop’s external dimensions, the thickness of its case and the shape of the laptop compartment all make a difference. Always check:

  • the maximum laptop size in inches;
  • the dimensions of the laptop compartment, if listed;
  • whether a protective case will still fit inside;
  • whether the compartment closes securely with a zip or fastening.

The NINETYGO backpack’s product name says it supports laptops up to 15.6 inches, while the product specifications also state “up to 14 inches”. That’s a clear reason to check the latest product information and measurements before buying.

2. Confusing water-repellent with waterproof

A water-repellent backpack can help keep out light rain and splashes. That doesn’t mean the contents will stay dry for long in a heavy downpour or if the bag falls into a puddle. Look out for the difference between:

  • water-repellent: the fabric temporarily slows water from soaking in;
  • weather-resistant: the material is designed for changing outdoor conditions;
  • waterproof: this usually requires sealed seams and zips as well.

For valuable electronics, consider using a separate laptop case or rain cover. According to the product information, the NINETYGO backpack isn’t fully waterproof, and prolonged exposure to heavy rain should be avoided.

3. Extra features that don’t add much in practice

A USB port on a backpack isn’t a built-in battery. You’ll need to bring your own power bank and connect it to the internal cable. Also check that the cable is still accessible when the bag is full. The product description for an anime backpack with a USB port claims that its luminous print can remain visible for several hours after exposure to light. This is the seller’s claim, not a guaranteed duration in all conditions.

Which features matter?

Capacity and compartments

For school or work, a well-organised layout is often more useful than a large capacity alone. Ideally, a school backpack should have:

  • a separate laptop compartment;
  • room for A4 books and a folder;
  • smaller pockets for keys, your phone and a charger;
  • side pockets for a bottle or umbrella;
  • a sturdy base that lets the bag stand upright on its own.

A 50-litre hiking backpack can carry more kit, but it may be unnecessarily large and heavy for your daily commute. As well as checking the capacity in litres, look at the backpack’s own weight. A large backpack made from lots of material can quickly become heavy when fully packed.

Material and care

The fabric affects how well a backpack stands up to everyday use. 900D fabric refers to a relatively high fibre density, but it isn’t a universal quality standard that predicts all types of wear. Also look for:

  • reinforced seams and attachment points;
  • quality zips;
  • a hard-wearing base;
  • how the shoulder straps are attached to the bag;
  • care instructions.

According to the product information, the NINETYGO is made from tear-resistant 900D fabric with a Level 4 water-repellent finish. Clean the bag with a damp cloth; machine washing and tumble drying are not recommended.

Carrying comfort and fit

A comfortable backpack distributes weight across both shoulders and stays stable when you walk or cycle. Look for:

  • padded, adjustable shoulder straps;
  • a breathable back panel;
  • a chest strap or hip belt for heavier loads;
  • a handle that doesn’t dig into your hand;
  • straps that don’t dangle while you’re cycling.

A military-style or outdoor backpack often has compression straps and several adjustment points. These can be useful on long walks, but overkill for a short school run. Adjust the straps with the bag packed so you can assess how it actually sits.

Frequently asked questions about backpacks

Which backpack is suitable for a 15.6-inch laptop?

Choose a 15.6-inch laptop backpack whose laptop compartment is specifically designed to fit that size. Also check your laptop’s actual dimensions and allow for a protective case. Don’t rely on the product title alone if the specifications contradict each other.

How long does a backpack usually last?

Its lifespan depends on the weight it carries, how often you use it, exposure to rain and cycling, and the quality of its seams and zips. A backpack will usually last longer if you don’t overpack it, keep sharp objects separate and follow the care instructions. Leave a wet bag to air-dry completely, and don’t store it damp for long periods.

Is a backpack with a USB port useful?

It can be useful if you often charge your phone while you’re out and about. However, the USB port doesn’t supply power by itself: you’ll need a power bank that fits inside the backpack. For everyday use, the cable’s position, how easy the port is to reach and protection from rain matter more than simply having the feature.
