I will take with me:
a compass
a first-aid kit
a map
a rucksack
pots and pans
boots
a sleeping bag
a waterproof jacket
I think that in the mountains a tent, matches, sewing kit, whistle, stove, carry mat are not necessary.
But a compass, first-aid kit, a map, a rucksack, pots and pans, boots, a sleeping bag, a waterproof jacket are necessary.
