You can walk any track in good conditions.

>>2697037 and other NZ tracks. Some people run them in singlets.
Loads are technical, but there’s a lot of them that are entirely fine to walk in jeans and cotton shirts and without gear, so long as you’re aware, and conditions are good.
Thing is, the longer and higher you go, the higher the odds become of finding not good conditions, and the more likely you are to get mentally drained and stop thinking.
In this sense, the meme is to pack for all foreseeable conditions, so you can push on and not die a noob death to fucking hypothermia. It’s also easier to teach than a risky “I won’t need X” mentality that should be reserved for locals.
This is extra important for guides as they tend to deal with people that are new to walking all day, know next to nothing about outdoorsy stuff, and are a danger to themselves.
For comparison, the landSAR group I’m with ascribes to the whole “gear for everything” philosophy generally, and especially to the public hiker due to missing being impossible to prep for and need to support a lost person, but they don’t give a shit if you as an operative go on a training mission with improper or insufficient gear, so long as you don’t die or show you’re a retard. Everyone’s local, experienced, know the area, and have been caught out without critical shit before.
