I wore this top for the first time out to the gym where I did 30mins on the elliptical, sweated a lot, and the shirt did not stick to me EVEN though I had the back tied a little tighter so it looked like a fitted top. I felt still at ease in the top. After that I did 30mins on a stationary cycle bike and -again- it stayed fresh. When I was done with my workout i took out the knot and I had the perfect ventilation because the back opens right above my mid back on me. It is a really great top.
