Comfortable as heck!! It doesn't lose its shape or get loose throughout the day which is exactly what I need to feel good after working out. I don't know about you but what I wear to workout affects my mood! It didn't make me feel very hot in them even in 90 degree F weather. I'm also short (5'1) and the length is finally perfect without me needing to buy a "petite"! This color is definitely seemingly less see through than the others on here. I would suggest wearing seamless panties or thongs though.
