I don't like Hanes, they always ride up on me. Try Jockey for women. You might also try to wear all cotton or linen shorts or crop pants. A little loose fitting so they will breathe better. I wear denim skirts on hot humid days too they are a lot cooler than shorts. A little extra body powder on my thighs, they don't get sticky. (sorry if that was aTMI)
Okay maybe another TMI but thong undies are a lot cooler on a hot summer day than panties, especially under a skirt.
