I've been searching for underwear to wear to CrossFit and have resisted trying any sort of thong. Boy was I missing out. I've worn these while playing soccer and during CrossFit and I couldn't be happier. In fact, the first time I wore them to try them out I completely forgot about them until I went to shower after my workout. I'd say that's a sign of good underwear! I also bought a pair of under armour pure stretch and like them much less. They were much more up in my business.
