In 2010, Castelli introduced the Gabba and changed the way cyclists ride in the rain. And cold. And ride in training. Every other cyclist soon saw the need for a Gabba in his or her wardrobe. Then we introduced Perfetto, Italian for "perfect," to give riders protection in every condition. Now, we are introducing Perfetto RoS, which signifies Rain or Shine. What this means is that you get exceptional comfort in dry weather, as well as nearly waterproof protection in the event that you get caught out in the rain.
