Good quality but a little short
I wouldn't say I'm above average height for a Medium, but I find the cut of the body a a little short, especially as the arms are quite long. I have found this to be fairly common of Arcteryx. Good quality as you'd expect, but a little oddly sized. (I'm a long time customer of Arcteryx and their cuts always seem to be very "athletic", without any of the length you'd expect). I feel the large would be a better length, but probably much too long in the sleeves and big in the body.
