What backpack size do I need?
The size of the backpack you need depends on three factors: the length and location or environment of the hike, as well as the season or the expected weather conditions. These three factors will help you determine the type and quantity of equipment you need, and therefore the size of the backpack to carry this equipment.
Backpacks for day hikes (less than 25 litres)
If you are out for a few hours, you usually only need water, one or two additional garments for weather changes, food and hiking poles.
Overnight Hiking Backpacks (1 Night; 25-35 Litres)
With just one night you dont have to have everything you need. Pack easily and the hike to camp and back will make you more fun. These backpacks can also be used for longer day hikes.
Backpacks for hiking and multi-day tours (2-4 days; 40-50 litres)
Longer tours require a larger backpack that can accommodate more food, cooking fuel and clothes to change in addition to camping gear.
Backpacks for longer hikes (5+ days; 60-75 litres)
Apart from long hikes, these larger backpacks are also good for parents who are planning shorter winter trips with younger children where extra warm gear is needed.
