I have clothing for the gym and clothing for running. The gym stuff typically doesn't work with a 20 mile run. I love how soft and neat the seams of the material are on the Boxstar clothing and have no problem at all running for a few hours in my Boxstar tanks. They are true to size, tapered for the ladies' tanks so there is no loose material to flap against me or snag on anything, no matter what kind of workout I'm doing.
What I like about this particular one is that it is black, it's simple and classic and really - every American girl should have a top with some stars n stripes :)
Love it. Fits perfect and comfortably
