>>2323332Good for you anon, just get out there as much as possible.
Dont worry about too fancy of gear, most people end up going full circle on gear. Starts with bare bones, then you start gear hoarding, then you realize you dont need much and return to essentials.
For water bottles, litterally just pick up 2-3 smart waters for a few buck. The bottles are pretty thick and can be reused for like a year +.
Boots arent really needed right away and really any tennis shoe or trail runner is my preferred for day trips and overnighters.
Sleeping arrangements are doable for as little as $30-40, if you are willing to sleep just under the stars, under a basic poncho or tarp, or in a hammock. But tents can be a nice option if you have a few bucks laying around. You can easily get away with a $20 fleece sleeping bag if it doesnt get below 40-45 degrees.
For eats, you really dont need to pack anything that requires cooking to start and can always upgrade cook systems down the line or just build fires if your area allows and you feel confident in making fire.
Other than that, maybe a small first aid kit, a little bit of cordage, some outer wear suitable to keep you warm and semi-dry. Maybe a small flashlight and you are pretty much ready.
Good luck anon.
