Choosing an outdoor backpack: how to find a model that suits the way you use it

An outdoor backpack needs to do more than look sporty. In the Netherlands, a bag has to cope with rain, mud, changing temperatures and often a packed train or bicycle basket. Yet many people choose a backpack based solely on its capacity in litres or a claim such as “waterproof”. This can result in a bag that becomes uncomfortable after just a few walks, offers insufficient protection or is awkward to use every day.

Joybuy Product Recommendation Officer therefore starts by looking at verifiable features: capacity, weight, carrying system, compartment layout and protection against moisture. These points make it easier to compare a walking backpack, trekking backpack or travel backpack.

Three common pitfalls when choosing an outdoor backpack

1. Choosing a large capacity without considering the fit

A large 50-litre backpack may seem convenient, but extra space encourages you to take more with you. Without adjustable shoulder straps, a chest strap and a hip belt, the weight can sit mainly on your shoulders. For a day walk, 18 to 30 litres is often more practical. For lightweight camping over several days, around 45 litres may be a better fit.

2. Confusing “water-resistant” with completely waterproof

Water-repellent or weather-resistant fabric helps in light rain, but it does not automatically mean that the seams and zips will remain waterproof for extended periods. Check whether a rain cover is included and consider using a separate waterproof bag for electronics or clothing. The product description for the OutdoorMaster Snow Sport Travel Backpack mentions water-resistant recycled fabric and a separate rain cover; that is more specific than simply using the term “waterproof”.

3. Confusing lots of compartments with a good layout

A backpack with lots of compartments can make it easier to stay organised, but small compartments also take up space. Think about what you actually carry: a laptop, water bottle, walking poles, waterproof jacket or cooking set. A separate hydration bladder sleeve and a front pocket for quick access are often more useful when walking than lots of small zipped compartments.

Which specifications should you check?

Capacity and dimensions

Capacity is stated in litres, but how useful the backpack is in practice also depends on its shape. Keep these guidelines in mind:

  • 10–13 litres: commuting, short bike rides and compact day-trip essentials.
  • 18–30 litres: day walks, hiking, use around town and short trips.
  • 45 litres: trekking or lightweight backpacking for around two to three days, depending on your equipment.
  • 50 litres or more: camping and larger quantities of clothing or equipment.

Also check the dimensions. A 30-litre bag may carry differently because of its narrow or particularly wide shape compared with a model with the same stated capacity.

Weight and carrying comfort

The weight of the empty bag matters too. A 1.35 kg backpack can be comfortable on long walks if the carrying system distributes the weight well, but for a simple day walk, a lighter model may make more sense. Look for:

  • a ventilated back panel to promote air circulation;
  • adjustable shoulder straps;
  • a chest strap to keep the bag stable;
  • a hip belt for heavier loads;
  • a suitable back length and waist size.

For example, the PELLIOT Trail Running Backpack links sizes to a torso length of 38–46 cm or 45–53 cm. This type of information is more useful than a general claim that the bag is “universally comfortable”.

Material and moisture protection

Nylon, polyester, Oxford fabric and Dyneema composite fabric have different properties. A coating can provide protection against rain and wear, while a lightweight material may be less suitable for sharp rocks or unprotected camping equipment. According to the product description, the Mobi Garden Phantom Pro uses Dyneema composite fabric and has a separate waterproof compartment for a hydration system. However, the manufacturer does warn that even this material can be damaged by forceful tearing or sharp objects.

So, a waterproof backpack is not automatically suitable for every type of terrain. Check the closure, seams, zips and included rain cover before carrying valuable items.

Practical checks before you order

Use this quick checklist:

  1. Measure your back length if the manufacturer provides sizing information.
  2. Estimate your load rather than choosing solely by maximum capacity.
  3. Check the moisture protection: coating, rain cover and zip construction.
  4. Look at the hydration system: is a water bladder included, or do you need to buy one separately?
  5. Consider care requirements: many models should be cleaned with a damp cloth and left to air-dry.
  6. Check the returns policy, warranty and contact details of the seller and the responsible party in the European Union.

A foldable backpack is useful as a spare during a trip, but it usually has less structure than a trekking backpack. For a laptop or fragile items, padded compartments are more important than a low empty weight. For camping, attachment points, weight distribution and material strength matter more.

Frequently asked questions about outdoor backpacks

How big should an outdoor backpack be for a day walk?

For most day trips, around 18 to 30 litres is sufficient. Choose closer to 30 litres if you are taking extra clothing, lunch, a camera or a hydration system. For a short walk with little luggage, 10 to 18 litres may be enough.

How can you make an outdoor backpack more water-resistant?

Use the included rain cover if there is one and pack electronics, documents and clothing separately. Close the zips properly and allow the bag to dry completely after a wet walk. Water-repellent fabric does not protect against prolonged or heavy rain in all conditions.

How long does an outdoor backpack last?

Its lifespan depends on the load, material, terrain and care. Avoid overloading, sharp objects and storing it for long periods in damp conditions or direct sunlight. Clean it according to the product instructions and regularly check the seams, buckles, zips and attachment loops.
