I bought this to use in late fall/early winter outdoor running, and it's been great so far. It's a pretty basic hoodie but the material it's made of keeps its shape nicely (the stretch doesn't come out of the sleeves, if you push them up during your workout), and it's lightweight, but warm and dries quickly.

The torso IS fairly long, which I wasn't sure about when I first put it on (I'm only 5'4" so it . falls a couple of inches over the tops of my thighs), but actually, I really like that since it doesn't let cold air in when the motion of your arms during jogging pulls the hem up. I'm fairly large busted (36DD) and wear a 10-12, and bought the large. (I think I could have gone with a medium if I wanted a tighter fit since it's stretchy and a little loose around the torso, but I prefer a looser fit when exercising. Just an FYI if others like a more streamlined fit.) Overall, a nice, basic piece of athletic gear at a good price!
