Belly bag
Although you naturally have a backpack, it is very practical to also use a belly bag to keep smaller and frequently used items to hand.
Hiking poles
Hiking poles are very useful on sloping trails. The telescopic hiking poles are practical as they are easier to stow in your rucksack and take with you. In most cases
usually fit into a suitcase when folded up and can be taken along without any problems.
