>>104672This so much. It was impossible for me to narrow it down to 4.
>First aidSelf explanatory.
>CamelbakSufficient water is essential. I suppose purifying water on site is a possibility but you won't always have any nearby and an easy way to transport it is also a necessity imo.
>BootsA good sturdy pair of boots with sufficient ankle support is mandatory for any length of walking. I prefer leather. Once properly broken in they'll be the post comfiest motherfuckers you've ever worn.
>Sleeping bagAnyone who's spent a night in winter with a shit sleeping bag and waking up several times in the night numb to the bone will appreciate this selection.
I would also consider a top notch waterproof jacket essential as well as a backpack with good capacity and back/hip support. Maybe make it 6?
