Fabrics for Activewear?

Hey guys, I've been wanting to start my activewear line for a while now, and one of the pain points I've been wanting to solve for so long is how activewear fabric tends to retain smell after prolonged use. I know the reason behind this is the retention of oils within synthetic fabric, right?

I just wanted to ask if you guys have ideas on alternative fabrics that are sweat-wicking but do not retain oil or smell after a period of time. I've been hearing about bamboo being an option?

Also, would appreciate any additional knowledge on activewear fabrics, I'm new to this. Thanks a lot!
