A backpack seems easy to choose until you start using it every day. That’s when you find out whether the shoulder straps adjust properly, whether your belongings fit neatly and whether the fabric can withstand rain and wear. Marketing terms such as “extra spacious”, “ergonomic” or “water-repellent” don’t tell you much on their own. Always check the capacity, dimensions, materials and compartments in the product specifications.
1. Focusing only on litres
A 30-litre backpack has more room than a 20-litre model, but that doesn’t automatically make it suitable for everyday use. A large bag can be unnecessarily heavy or awkward if you mainly carry a laptop, lunch and sportswear. Check the dimensions and the backpack’s own weight too.
2. Confusing water-repellent with waterproof
According to the product description, polyester, nylon and coated materials may offer protection against light rain or damp. That doesn’t mean the backpack will stay waterproof for a prolonged period. If you cycle in changeable British weather, you may need extra protection, such as a rain cover or waterproof inner bag.
3. Assuming more compartments mean better organisation
A backpack with several compartments is practical if they’re large enough for your belongings. Small zipped pockets are handy for keys and accessories, but they can reduce the space in the main compartment. So check where your water bottle, books, clothes and electronics will actually fit.
Choose a capacity that suits how you’ll use the backpack:
A 20-litre backpack is usually compact. A 30-litre backpack gives you more flexibility for clothes and accessories. A 50-litre backpack is mainly worthwhile if you really need to carry a lot of kit.
Look for padded shoulder straps, a supportive back panel and straps that can be adjusted properly. For walking, hiking or trail running, a chest strap and sometimes a hip belt can help keep the bag stable. A breathable mesh panel may improve airflow, but it won’t prevent you from sweating in every situation.
Check the fit too. A unisex backpack can be worn by different people, but fit is still personal. For trail running, a close-fitting model is generally more practical than a loose school backpack.
Many models are made from polyester, nylon, polyamide or Oxford fabric. According to the manufacturer’s product description, coatings and woven fabrics may help improve wear resistance or water resistance. Treat these as product specifications, not as a guarantee of a particular lifespan.

We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and the applicable European safety regulations.
For a laptop, books, lunch and a few accessories, 20 to 30 litres is usually practical. As well as checking the capacity, make sure your laptop will actually fit in the designated compartment. A smaller model may be enough if you’re only carrying sportswear and a bottle.
Always follow the manufacturer’s care instructions. Many models can be wiped clean with a damp cloth. Don’t assume that a coated backpack, or one with zips or padded sections, can go in the washing machine. Leave a damp bag to air-dry and avoid direct heat, unless the product information says otherwise.
A hiking backpack often has features such as chest or hip straps, a breathable back panel, compression straps and easy-to-reach pockets. These features aren’t essential for a short walk around town. For longer walks or a trail running backpack, stability, low weight and easy access to drinks matter more than a dedicated laptop compartment.
