I guess I would say I am not a fan of these.  They fit kind of strange, pull a little in the back, and are very heavy.  I do sweat when working out, and I always want to feel like I am not carrying extra weight.  With this top, I definitely feel uncomfortable.  I guess that's why I never wear them.  They have been in my drawer and have not been used.  The designs are cute.  The shirt and fit?...not for me.
