We're keeping on two wheels and staying comfortable in the GORE WEAR Formula Vest. This vest is extremely lightweight, and we're wearing it on those somewhat chilly days with strong winds. The windproof layer keeps the heat sapping wind off us, so we're able to ride longer and get todays training out of the way. When we're warmed up and ready to take the layer off, with some effort we're able to stuff it into one of our jersey pockets.
