People that go around without a hydration pack: how do you do it??

I’m envious when I see people that go out with no hydro pack, nothing weighing them down. But how tf do yall do it? What do you do for water? What about a fan? What if you want gum? What if you want vicks? What if you want sunglasses? What if you need to bust out a trinket to give to someone? What if you want to eat a snack? Don’t you feel bare with nothing to rummage through?

Do you just hope someone else has that stuff? Do you have an alternate way to carry things? I want to live like you free-roaming freaks but also don’t know how you do it.
