I just tried out my new Velo Bella vest yesterday. What I liked: very good at both keeping my core warm (it was in the mid50s at sunrise when I started out) and the mesh fabric at the back was excellent at venting so as it got warmer, the vest remained comfortable. It's folds up nice and compact, so you can easily stash it if you decide to take it off. I wear a size Small and I found the cut a bit generous. The only bummers were: (1) the zipper is NOT multi-directional; (2) the elastic at the bottom rides up so you end up with "puff" at the tummy, if you know what I mean. I like that it's longer, but it's kind of self-defeating since it ends up creeping up your body to your waistline. If it had the dual-action zipper, you could unzip from the bottom to alleviate the problem.
