    It does what it claims it does. True to size and feels comfortable. When you perspire it does not get weighed down, great.

    Comfortable but a little tight

    Its a great workout shirt but a little too tight for my needs. I like a little extra room in my workout clothes. If that doesn't bother you, then I would recommend. If not, definitely go a size up.
