Question: how many litres backpack do i need?
Answer: Rucksacks can range from 5 litre daypacks to 85 litre monster travelpacks! There is no need to buy a rucksack that is more than 70 litres at the VERY maximum. The perfect size for most people is 60l, although generally girls are better off with 50-55 litres, and lads are better off with 60-65 litres.
