Well, that looks pretty nifty. I saw this piece in store the other day, and was immediately drawn to it, probably because it has so many bells and whistles. The store associates made my friend try it on, then took a picture of her it in to show its reflectivity. She glowed like a super hero, so cool. There seems to be mixed reviews on it, but it seems like a matter of preference. I’d say it is heavier than I’d prefer for running, and it also costs about a dollar per degree of reflectivity. To each his own.
