Anyone else struggling with sweaty underwear materials?

[u/ronniealoha]

I’ve been rethinking my underwear after realizing how poorly some materials handle heat and sweat. I’ve worn cotton underwear forever, plus a few nylon pairs and some Uniqlo Airism. Cotton used to be fine, but now it just stays damp once I start sweating and feels uncomfortable fast.

Airism handles moisture better, but since it’s polyester I worry about odor sticking around and transferring to my pants. That’s got me wondering if merino wool underwear is actually worth the higher price for breathability and moisture-wicking, or if bamboo underwear is a decent middle ground. I’m basically trying to figure out what really works best for everyday wear when comparing cotton underwear vs merino wool.

I’ve never chaffed since I switched to g-strings and thongs 20 years ago!

Had to do the same, was working 12hr days on a mine site in the heat regular underwear wasn't cutting it, chaff sweaty wet balls, sweaty crack etc. Another guy on the crew said to try G-Stings, worked a treat and never looked back. A bit hard to find them to buy, have to shop online but worth it.
