Seeking advice for/from women on best ways to manage sweating while recreating

I love being outdoors hiking, kayaking and exploring but there is just one problem...sweating and its excessive.

I'm 53, post menopausal and live in  central Texas. After hiking and sweating so much, my cargo pants/capris look like I didn't make it to the restroom in time! 

Are there any moisture wicking underwear/shorts/ pants that alleviate this problem?

Thanks in advance. 😅
