Use to be super into hiking and camping. sort of just stopped and sold off the stuff I had.
One of the guys I hiked with was super careful about his carry weight, the guy would drill holes in his toothbruth to reduce it's weight.
proper boots and insoles always felt most important, bring some mole skin to patch around blisters.
Leukotape is the best thing to patch yourself up when on the trail. That's like the one products no nonsense products you should have in your first aid kit.
