This is gonna seem like a lot of stuff, but it all fits into pockets, onto belt and into a 600ci rucksack. Depending on time of year, the off the beaten path trails can be hazardous and at my age, pretty much anything can happen while out, so I carry what I take hunting, which will hold me for several days, in case of injury or I decide to stay an extra day or so cause I'm having a lot of fun.
