The Hiking Pack is a larger backpack that unlocks 4 slots. It is very useful for long trips or just carrying things. They are fairly uncommon but a Survival Pack would be much more useful. Before the Kin Reimagined update, they were always orange in color.
You can spawn with the hiking pack, which costs 1 credit at the spawn menu. The color is randomly chosen. This is one of the least popular spawnitems, due to the abundance of them in-game.
It is often used to carry civilian supplies. It has 16 slots.
