I tried this out for running and swimming yesterday hoping to wear it for my first triathlon coming up in a few days. It looks great on and fits well (I ordered based on the size chart), and It was great for the run. Unfortunately, I only made it half a lap in the pool before deciding it was not made for the water. While swimming, the top catches water like a parachute creating a HUGE drag and making me feel like my boobs were going to fall out. I tried another lap, and gave up, bummed that I spend $80 on a running top.
