Knicker recommendations for sweaty gym classes and hot/humid climates

[Speckydots]

I wear 100% cotton knickers all the time - they're not expensive, but they are always cotton. I tend to wear bikini shape or sometimes high/full pants.

But I've noticed in classes that my ass (sorry, I know this isn't the nicest of topics) feels hot and a bit sweaty. I'm also off to a humid climate, so this could be the albatross of the holiday.

Any suggestions for not-too-expensive marvellous knickers for the above?

Stnthetic sports or running knickers with breathable mesh panels for workouts. I wouldn't wear them all day every day, but they stop the chafing heavy feel. For hot weather, I wear cotton thongs. I know they're hated on MN, but for me they're the most comfortable option because they don't rub, dig in or collect sweat.
