At least it's what I was told, on a different mountain range and continent, by a Seattleite guide who volunteered to lead a group of hikers around the base of Mount Rainier in Washington.
So strong was his conviction that hiking should only be done in pants specifically designed and designated for hiking that he kept a spare pair in his Subaru — a car specifically designed and designated for taking oneself to the hike — and insisted I change out of my jeans and into those pants before we start.
Now, with over a decade of hiking experience, I know with certainty my pants had zero negative effects on those trips. On the contrary, there are great benefits to just going with the simple solution you have on hand:
And now, with over a decade of startup experience, I know there are loads of opportunities outside of hiking where first doing things "in jeans" is the better (yet non-obvious) choice.
For example, if you want to test a new way of talking about your product, you can do it with a handful of informal user interviews, a simple LinkedIn poll, a webinar with the messaging as its theme, or with the trial version of a simple testing tool like VWO. You don't need a six-month long branding project, an enterprise experimentation platform that would cost $100k+ and take months to implement, or a large-scale and expensive usability-testing solution... All of which were real suggestions people made and almost committed to before I intervened.
