Castelli made the Aero Rain Lite LS Jersey for riding in cold, wet weather. The Windstopper® X-Lite Plus fabric is new for the winter 2011 season. Lightweight and stretchy, this cycling jersey blocks out wind and rain but at the same time it is breathable so your high-intensity cycling performance will be enhanced. Nano-Flex fabric inserts under arms absorb sweat and wick it away. By keeping your body dry, your temperature is regulated so you stay within your ideal performance temperature range. This will also help you stay comfortable in rough weather. Storm-flap construction at back protects you from that mucky wetness that comes up off your wheels. Silicone gripper on waistband keeps the jersey from riding up so you stay dry, warm and comfortable. You can open up the front zippered chest vents when your body heats up and you need a little cooling. The jersey is easy to slip on or take off because of the front full-length YKK® Vislon® zipper. Three rear pockets with eyelet holes give you plenty of room to store your riding food. Rear reflective tabs and trim for high visibility. Ideal for temperatures ranging from 40F to 60F (>7C < 15 C).
