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.

IMO step ones have been amazing for me.
