He lives in a hot place. So i expect the answer would be yes.
So do i
Trust me, Jeans in hot climates are not life threatening but they are still a terrible terrible choice and mega uncomfortable, even for sitting around drinking beer in.
Don't get me wrong mate. I whole heartedly agree. I'd never wear jeans on a serious trek. And I'd be taking a base layer at the very least depending on the conditions.
I'm just saying that jeans aren't enemy number one for day to day stuff or a summer overnighter in the uk. (assuming dry weather)
Perhaps this thread should be steered towards what should be worn, the importance of layers and how to stay warm in a good sleeping bag.
As has been pointed out, money is a major factor. I can't afford the high end fabrics, that's where surplus kit comes in handy coupled with long johns and a waterproof outer if needed.

Thing is though Andy the thread was started by a op that had a miserable and cold night out.
Part of the reason he had a miserable night out was because of a bad choice of sleeping mat and because he was wearing Jeans.
It makes absolutely no difference at all if you wear a base layer under your jeans if they are soaked.
That could be from rain but it could also be from sweat.
An active day hiking builds up sweat on warmer days, as Jeans take hours or even days to dry in some climates if you then continue wearing your jeans in the night you'll inevitably get cold.
Preventing hypothermia is as simple as taking off wet clothing and getting into a sleeping bag. Just like they teach in SERE school.
Heat retention is as simple as wearing a good set of long johns (and yes, I like wool or polypropylene for those) Or are your pants your only piece of clothing?
Quick drying? Irrelevant if you get wet again in 5 minutes.
Didn't help the op have a nice comfortable night though did it mate?
Plus how many people take a sleeping bag on a day hike?
If you were expecting colder or wetter weather surely you'd be better off just wearing the appropriate clothing, i.e. not Jeans?
Sorry if i'm coming across a bit strong here mate, i know we've disagreed before and managed to keep iot light hearted.
It's just on this subject i feel very very strongly about it.
So if i come across as being a bit too strong or a bit sarcastic i apologise and can assure you i have the utmost respect for you, your experience and your opinions :You_Rock_
Cheers
