I bought this top for my first triathlon, and it worked great. It dried quickly and was comfortable. I do recommend going a size bigger if you're not sure.
I am planning on wearing this top in my first traithlon in June so I did a trial run just the other day. I was a little worried because I ordered a size bigger than usual and still had to keep pulling it down over my belly but I am just self conscious about that anyway. However, once I got into the water it felt really good, very lightweight, no drag and I had complete range of arm motion. After swimming in it I blasted across the hall to a spin class and rode for an hour in it soaking wet expecting to feel a bit soggy the whole time but ended up being really comfortable. Then I went upstairs to do an abs class and the only drawback with this was that I felt like I had to pull it down all the time again. When it was wet it stayed down and it wasn't on my mind as much but as it dried it pulled up a bit. Maybe I just need to spend more time in abs class!!
