Adidas

This is my all-time favorite underwear for working out. They’re on the expensive side, but worth it in my opinion. These Adidas Climacool thongs do everything a pair of workout undies should do: They stay put (no riding up or rolling down), they stay dry, and they don’t show your panty line through clothes — not even through tights. 

If you don’t like thongs, Adidas also makes “cheeksters” in the Climacool fabric.
