Castelli Cycling Men Alpha RoS Light Jacket Red/Black Large L
ALPHA ROS LIGHT JACKET WIDE COMFORT RANGE, RAIN OR SHINE We call it a light jacket but the comfort range is surprising. It dips well into temperatures where you might normally reach for a full protection jacket, yet the surprising breathability makes it still comfortable in temps when you may have worn arm warmers and a vest in the past. And it keeps you dry. RoS stands for Rain or Shine. It’s a label we give our most advanced products that excel in both dry and wet conditions. For dry conditions, you’re looking for comfort along with breathability to prevent you from getting wet and chilled from the inside. But with wet-weather clothing, you’re looking for protection that will help you stay warm by keeping the rain out and letting sweat escape. The Alpha RoS Light Jacket ticks both of those boxes. Both the front and back materials represent a significant step forward in rain protection. These fabrics are used with reduced seaming, and seam sealing where necessary. We call this functional waterproofing because while we don’t guarantee that no drop will ever enter the jacket, we promise you that this is our best effort to keep you warm and dry in the widest range of conditions.
