Sierra - June and July, usually that means no rain and even lower humidity...(I know, but usually).
I too confess to wearing cotton...almost live in a loose, long sleeve, 100% cotton shirt. (the thick, well-made, mosquito-proof kind.)
Been doing this for years - Not dead yet.
Here's a flash...Cotton shirts work well in our dry conditions!
But maybe I don't get out enough...
BTW, on trips over 12 nights, I do carry another shirt too - synthetic but prefer the cotton.
