Have you ever wore a tyvek? When I was a painter for Caterpillar,our paint booth got up to 118* one summer. We were in our underwear and still sweating through that damn suit.. It was the worst day ever... To this day I only wear them if I have to. LOL
Tyvek isn’t quite the same as Gore-Tex. Gore-Tex breathes a lot better because the technology is more advanced that Tyvek. (I used to work for DuPont :D)
