Choosing a hiking backpack: find the right model for day hikes and trekking

A hiking backpack needs to do more than just carry your belongings. Whether you’re walking in the Veluwe or the Ardennes, or heading out on a multi-day trek, you’ll soon notice whether the fit is right, the compartments are practical and the material can stand up to rain and abrasion. A model that looks roomy in a product photo may prove uncomfortable to carry or simply too heavy in use.

As a Joybuy Product Recommendation Officer, I’ve picked out the key product specifications and common pitfalls to help you compare your options more easily.

Common pitfalls when choosing a hiking backpack

1. Looking only at the capacity in litres

A 30-litre hiking backpack may be suitable for a day hike, but its usable capacity also depends on its shape and layout. A deep main compartment without external pockets may be less practical than a slightly smaller bag with well-organised storage.

For two to three days, a 40- to 45-litre trekking backpack is often a good choice. A 50-litre hiking backpack offers more room for camping gear, clothing and food, but it can also be heavier and bulkier. Choose based on the gear you’ll be carrying, not just the biggest number.

2. Mistaking “waterproof” for completely watertight

Terms such as water-repellent, splash-resistant and weather-resistant don’t automatically mean a bag will keep out prolonged rain. Check whether it comes with a rain cover, sealed seams or a waterproof inner pocket.

A separate hydration bladder compartment, as found on some trekking models, won’t necessarily protect the rest of your gear. If in doubt, put electronics, documents and sleeping gear in a separate dry bag.

3. Overloading a lightweight backpack

A lightweight backpack is appealing for walks where every gram counts. However, thin material or a limited support system may not be suitable for a heavy camping load. Check the stated load capacity, the weight of the bag and whether it has a hip belt.

According to the product information, the PELLIOT 40L has a stated load range of around 11 kg. No comparable maximum load is given for the Mobi Garden Phantom Pro 45L. That doesn’t mean it’s unsuitable, but it does mean you should compare options particularly carefully if you’ll be carrying a heavy load.

Important specifications to check

Capacity and layout

Use this practical guide:

  • 10 to 15 litres: short walks, trail running, commuting, or as a spare or foldable backpack.
  • 20 to 30 litres: day hikes with a jacket, lunch, drinks and an extra layer.
  • 40 to 45 litres: lightweight backpacking or a two- to three-day trip.
  • 50 litres: camping and longer trips with more gear.

Look at the access to the main compartment, side pockets, hip belt pockets and attachment points for walking poles or a sleeping mat. A camping backpack will usually benefit more from attachment loops and compression straps than from lots of small internal pockets.

Carrying comfort and fit

A backpack with a hip belt transfers some of the weight to your hips. An adjustable chest strap helps keep the shoulder straps stable. For larger models, check your torso length too. The PELLIOT 40L, for example, is available in sizes S/M and L/XL, with different torso lengths and hip measurements.

A backpack with a breathable back panel can improve airflow. That doesn’t guarantee your back will stay dry: temperature, clothing, exertion and how the pack fits all play a part too. A 3D suspension back panel, ventilated mesh or an EVA panel are specific design features you can compare.

Material and care

Dyneema Composite, nylon, polyester and coated Oxford fabric all have different properties. Don’t just look at the material name; also check:

  • tear and abrasion resistance, according to the product description;
  • protection against rain and splashes;
  • care instructions;
  • susceptibility to sharp rocks or sticks;
  • the weight of the material and the bag.

The Mobi Garden Phantom Pro product information states that Dyneema Composite is lightweight and abrasion-resistant, but also warns against sharp objects and prolonged exposure to sunlight. This is useful to know if you’ll be using the bag frequently on rocky trails.

Frequently asked questions about hiking backpacks

What size hiking backpack do I need for a day hike?

For an average day hike, 20 to 30 litres is often enough. If you’re taking lots of clothing, a camera, extra food or a sit mat, 30 litres may be more practical. For trail running or a short walk with little luggage, 12 litres may be sufficient.

Is a water-repellent backpack enough in the rain?

A water-repellent backpack will generally protect against splashes and light rain, but it won’t necessarily keep your belongings dry during prolonged exposure. Use a dry bag for valuables and check whether a rain cover is included or available separately.

How long does a hiking backpack last?

Its lifespan depends on the material, load, care and conditions of use. Clean the bag according to the instructions, dry it completely before storing it and avoid overloading it. Check the seams, zips, buckles and attachment loops regularly, especially after walks on rocky trails.
