I wore this for running in the middle of summer. It's sheer on its own, so I wore it over a red NIKE sports bra that I'm also selling separately. It's lightweight and quick-drying. There's a stain on the back, but it looks like it will come out with washing. There's also a small fray on the left shoulder, but it's not noticeable at first glance. I also wore this for yoga! I'm also selling other marathon gear!
