Fit is fine, but the identical one in brown color I bought just "feels" better somehow. I think the fabric they use for the heather is just a different "brush" or something. It's too soft and silky for my tastes and I overheat a bit. I prefer the non-heathered fabric because it breathes better and my body respires like a crazy-active high school athlete's even though I'm in my mid-40s.
