Castelli is serious when it comes to battling the elements, and they've amped up their Emergency Rain Jacket to offer the Emergency 2 Rain Jacket. It's ideal for wet weather and breathes so well that many top-class athletes reach for this jacket in inclement weather during the spring classics. While it's not meant to be an all-day rain jacket, it's designed to tackle wet weather in stride when the weather takes an unexpected turn for the worst.
