Sports bras are supposed to fit snugly, but not quite this snugly. Some makers are too cheap to use a good zipper, and this one is nylon. I think. If you don't want a wardrobe malfunction, don't buy too small, and avoid those that don't have a backup hook underneath. This one doesn't, nor can the zipper be trusted. And yeah it can certainly malfunction, if you run. Suits me. Love to run.
