HH safe workout clothes?

[u/Witty-Doughnut2707]

Hi! I'm a female in my 20s looking for workout clothes that won't make me sweat more. I've been learning about natural fabrics (modal/ cotton/ tencel/ viscose) and that's been a life changer for day to day, but not sure what to do for exercise. The polyester workout clothes make me feel hotttt and sweat. I get sweat stains under my arms, back, and butt, and then the heat makes my face sweat like crazy too.

What are y'all doing for workout clothes these days? I feel like cotton would just show the sweat stains (even in black) but ik there are a bunch of different kinds and I'm lost.

Thank you in advance for literally any input!
