How to choose a daypack for hiking

A daypack is simple to describe and surprisingly easy to get wrong. A pack that is too big encourages you to carry more than you need, and one that fits badly gets uncomfortable well before the end of a walk. This guide explains the main things to compare, so you can judge a pack on how you will really use it.

1. Start with what you will carry

Before looking at packs, list what you plan to take on a typical walk: water, food, extra clothing, a first aid kit, navigation, sun protection and anything you carry for others. Government and park guidance consistently stresses carrying plenty of water, protective clothing and navigation and communication gear, so your list will shape the size you need.

2. Capacity, in litres

Pack capacity is usually given in litres. One retailer's guide describes daypacks as running from about 10 to 40 litres, with around 20 litres suiting many people, but the right size depends on the season, the length of the walk and who you are carrying for. Cooler weather and longer walks need more room for layers. Smaller packs are slimmer with fewer pockets, while larger ones add organisation and attachment points. Measure against your own list rather than chasing a number.

3. Fit matters more than features

Torso length is generally described as the main factor in pack fit, measured from the top of the hip bones up to the base of the neck. Many makers publish a fit chart or sizing guide, so check it, and try to fit a pack with a realistic load in it. The shape and length of the shoulder straps also affect where the weight sits.

4. The hip belt

A supportive, load-bearing hip belt can transfer some weight from your shoulders to your hips. A simple waist strap mainly helps keep a lighter pack stable.

5. Ventilation and comfort

Australian walks are often warm. Look at how the back panel handles air flow and heat. A suspended mesh back panel or ventilated design can improve airflow. The amount of ventilation depends on the design, fit and conditions. Consider how much of your back is covered by padding, and how that feels in your climate.

6. Carrying water

Many daypacks include a sleeve for a hydration bladder and a port for the drinking tube. Others rely on side pockets for bottles. Choose the method you will actually use, and think about how easy it is to reach water without removing the pack.

7. Weather protection and organisation

  • A rain cover or a water-resistant fabric can help in wet weather. Check whether a cover is included or sold separately.
  • A rain cover or water-resistant fabric does not guarantee dry contents. Consider a waterproof liner or dry bag for items that must stay dry.
  • A sternum strap steadies the shoulder straps on uneven ground.
  • Compression straps keep contents stable and reduce volume when the pack is not full.
  • Pockets that suit your own items, such as a hip-belt pocket for snacks or a phone.

8. Check the details before you buy

  • Is the stated capacity for the whole pack or the main compartment only?
  • Can the straps and hip belt be adjusted to your body?
  • What does the maker say about the pack's weight and the load it is designed to carry?
  • How easy is it to repack and reach items while walking?
