Great jacket. The Gore-tex Infinium fabric makes this highly wind-resistant, breathable, yet very water repellent. The fit is spot-on, and the construction is excellent. Wear this over a light jersey or base layer in cold or cool and windy conditions or when light rain is possible. The fabric is light and fairly soft, although a bit bulky to be stuffed in a jersey pocket, so don't plan on taking this along "just in case", but instead treat it like a jersey that you will wear for the entire ride.
