I'm planning to go to Tasmania for a few months to basically hike around the whole place. I've been told by some people that I will need thermal underwear, where others have said I will need sports underwear. However, I don't wear underwear at all; I stopped where it about a year ago because I failed to see a reason to where them. I also found on very hot days(45 Celsius+) if I walked around a fair bit or done some exercise I would develop rashes from all the sweat the cotton underwear would suck up.
So, I'm basically asking is underwear useful whatsoever?
