Water goes from stream to nalgene. Iodine goes in the bottle. Water then goes into jet boil where it is boiled then put into camp food pack. Was just listing all the things I actually needed to eat and drink.

Years of hiking and backpacking and camping you learn what you will need, what you might want to have with you and what you probably don’t need. Again, experience can replace a lot of gear, either by realizing what sort of gear you actually need or eliminating that piece entirely. I’ve made a lot of mistakes and still make them but every time you go back out you do things differently, better. And I can honestly say I would never bring a stainless steel water bottle on a hike. To me that’s like bringing your camera, your laptop and CD player when you could just bring your phone. Why carry all that when I could bring a nalgene and a jet boil for the same weight and it’s easier to use that way?

It’s the people who have a false sense of knowledge who think they know what they’re doing out there and think they’re making the right choices on gear, route, etc that end up needing a dangerous rescue. It’s a false sense of experience and you can see that come out when someone says stuff like they’d bring a heavy stainless steel water bottle and use it to cook. Experienced people will scratch their heads at that. Knowledge comes from experience. Either your own or from talking to others with experience.
