Choosing a hiking backpack: a practical buying guide for day trips, trekking and camping

A hiking backpack needs to be more than just spacious. The fit, weight distribution and rain protection all affect how comfortable you’ll be on the move. A cheap buy can prove impractical if the shoulder straps dig in, the back panel doesn’t ventilate well or the stated capacity doesn’t suit your kit.

Common pitfalls when choosing a hiking backpack

1. Looking only at the capacity in litres

A 40-litre backpack, 45-litre backpack or 50-litre backpack won’t necessarily be comfortable to carry. A 50-litre backpack with a basic back system may be less comfortable than a well-adjustable 40-litre model. So look for a hip belt, chest strap, adjustable shoulder straps and, where relevant, a frame.

2. Confusing water-repellent with waterproof

A water-repellent backpack will usually protect against light rain and splashes. That’s not the same as a fully waterproof bag with taped seams or a waterproof roll-top closure. Check the product description, and use a separate rain cover or waterproof dry bags in prolonged rain, unless the manufacturer clearly states that the bag offers a higher level of protection.

3. Overloading a lightweight design

A lightweight backpack is handy for long walks, but the fabric, straps and back support all have their limits. According to the product description, the Mobi Garden Phantom Pro is designed for lightweight backpacking and a suitable load. A framed backpack, such as the PELLIOT 40L, makes more sense if you regularly carry heavier camping kit.

Which specifications matter?

Capacity and trip length

For a day trip, 10 litres is often enough for water, a jacket, lunch and a few accessories. For a camping backpack or a backpack for multi-day hikes, you’ll usually need more capacity:

  • 10 to 20 litres: commuting, short walks and minimal day-trip kit.
  • 30 to 40 litres: compact camping kit or a trekking trip lasting a few days.
  • 45 to 50 litres: more room for sleeping gear, clothing and cooking equipment.

The capacity you need depends on your kit. A large main compartment isn’t always more practical if it makes smaller items difficult to find.

Comfort and fit

Check whether the hiking backpack has:

  • An adjustable hip belt that shifts some of the weight onto your hips.
  • A chest strap to keep the shoulder straps stable.
  • Shoulder straps with enough padding and ventilation.
  • An adjustable back length or multiple sizes if your build is outside the usual range.
  • A back panel that allows air to circulate.

The PELLIOT Trekking Backpack lists the recommended torso length for each size: S/M for 38–46 cm and L/XL for 45–53 cm. Before choosing a trekking backpack, measure from the prominent bone at the base of your neck to the top of your hip bones.

Material, weight and organisation

Compare more than just the empty weight: check the storage options too. External attachment points are useful for walking poles or a sleeping mat. A separate hydration bladder compartment, side pockets and a front pocket can save time on the move.

According to the product description, the Mobi Garden Phantom Pro 3D Dyneema uses Dyneema composite fabric, nylon webbing and UT-DURAFLEX buckles. The manufacturer says the material is lightweight and tear-resistant. This is a product claim; sharp objects can still damage this type of fabric. The bag weighs around 1.35 kg according to the specifications and has a capacity of 45 litres.

Frequently asked questions about hiking backpacks

How big should a hiking backpack be?

For a day trip, 10 to 20 litres is often enough. For a multi-day trek, 40 to 50 litres is usually more suitable, depending on your tent, sleeping bag, clothing and cooking equipment. Don’t automatically choose a bigger bag: the extra space could tempt you to bring things you don’t need.

How do I adjust a trekking backpack properly?

First, pack the heaviest kit close to your back. Then adjust the hip belt so it sits securely without digging in. Next, adjust the shoulder straps and fasten the chest strap. Walk for a few minutes and readjust if the bag pulls backwards or presses on your shoulders.

How long does an outdoor backpack last?

Its lifespan depends on how you use it, what you carry, how you store it and how well you maintain it. Wipe off dirt with a damp cloth, let the bag dry completely, then store it somewhere dry and out of direct sunlight. Check the zips, buckles, seams and straps regularly. Always follow the manufacturer’s care instructions and don’t exceed the stated load capacity.
