This is a really great running jacket. I've done a few outdoor, warm and cool weather runs and a few races with it. It breathes but doesn't let wind through and a pretty decent amount of moisture. The only strange thing is that, at least for me, the sleeves are disproportionately large in relation to the chest size. The chest fits me perfectly but the sleeves are too big. There's nothing wrong with that, it just looks silly and a little annoying. But overall it's a really great jacket. Although it would be possible to use multiple pockets on the front.
